prepared for use as a topical treatment with the particles being directly administered onto the skin in
the form of either lotions or gels or ointments to treat skin disorders and promote healing. They can
also be used orally, for example in the form of powders or capsules as dietary supplements that
enhance systemic immunity and general health [26]. Various nanomedicine delivery approaches,
such as liposomes, nanoemulsions and microemulsions, were used to improve the bioavailability and
therapeutic efciency of these phytochemicals. These systems were developed with the intention of
optimizing therapy outcomes for specic diseases and were intended to be administered via a variety
of routes, including topical, oral, intranasal, and intravenous [23].
19.3.2.1.3 Patient Response
Herbal nanoparticles have received generally excellent feedback in both clinical and preclinical
preferences, which is indicative of their improved therapeutic potential and sophisticated delivery mechanisms. Patients receiving therapy with these novel formulations have reported signicant
improvements in both their general health and their ability to manage their diseases.
For example, patients receiving Phytolacca decandra- encapsulated nanoparticles in cancer ther-
apy have seen a notable decrease in tumor size and improved overall results when compared to
patients getting conventional therapies [23]. Herbal nanomedicine therapies have demonstrated
favorable outcomes for patients, as evidenced by increases in antioxidant defense and a decrease in
symptoms associated with oxidative stress. The biocompatibility and stability of the nanoparticles
contribute to their efcacy in reducing oxidative damage and battling microorganisms and cancer
[24]. The promising results from these treatments include: large decreases in lung cancer metastatic
foci dimensions and tumor biomarkers; strong antitumor activity in liver cancer models; and highly
effective targeted drug release in breast cancer. As reported in the same study, curcumin- based
micelles boosted pro- inammatory cytokines and had synergistic antitumor effects in treating [24].
In a similar vein, patients have had improved treatment outcomes and fewer side effects with the use
of nanocurcumin, proving its efcacy in treating a range of malignancies. Iin the eld of antimicrobial treatment, patients utilizing Ocimum sanctum or Harungana madagascariensis- formulated
nanoparticles have demonstrated successful control over infections, particularly those produced by
resistant strains [23]. Treatments involving Cuscuta chinensis- loaded nanoparticles have enhanced
liver health by lowering oxidative stress and improving liver function. Patients given this treatment
have reported an improvement in liver health overall and improved treatment of liver diseases.
Comparing ginsenoside Rg3 micelles to untreated controls revealed less myocardial damage and
also retained cardiac function. Again, in treated animal models, the levels of oxidative stress indicators and inammatory cytokines were reduced through the use of purrarin and curcumin treatments.
Drug stability and distribution were enhanced using liposomal and polymeric nanoparticles, leading
to better clinical results and fewer adverse effects than experienced under conventional therapies.
Preclinical research revealed that nisin- loaded nanoparticles were well tolerated and non- toxic,
improving ECG patterns and lowering indicators of myocardial injury [25]. In further evidence of
the effects, aloe vera NP- based herbal nanomedicine therapies have been shown to improve skin
health. Patients have reported better skin texture, less inammation, and faster wound and skin condition healing. Most patients report excellent results from the therapeutic uses of herbal nanomedicines, and most have great tolerance and experience little in the way of side effects [26]. Following
treatment with these nanomedicine therapies, patients and animal models experienced notable
improvements. These included decreased tumor size, improved liver function, better protection
against brain ischemia, increased antiviral activity, and an effective reduction of inammation [23].
19.3.2.2 Analyzing Clinical Findings to Rene Treatment Approaches
The clinical results analysis is a crucial method of improving herbal nanomedicine treatment.
Through the close examination of patient data, scientists can nd out such things as relationships,
patterns, and trends which in turn help to ne- tune the treatment plans. The major spheres of concern are to examine the patient response diversity, to consider the safety and tolerability, to measure
Implementing Herbal Nanomedicine in Clinical Settings 405
the therapeutic effectiveness, and to relate the pharmacokinetics and the pharmacodynamics. The
data is analyzed with the help of advanced methods such as articial intelligence to obtain predictive
models and apply personalized medicine. Constant observation and assessment are the two key factors in the improvement of long- term therapeutic efcacy and the generation of data that will prove
the efcacy and safety of herbal nanomedicine.
Clinical symptoms are of great importance in enhancing the effectiveness of therapy and improve
treatment practices. This can be achieved by examining the laboratory studies, patient data, and
advanced diagnostic techniques. To illustrate, the microbiome of the gut has an important contribution in the pathogenesis of such diseases as colorectal cancer and inammatory bowel disease.
Probiotics and prebiotics are two personalized treatments that have been developed in clinical
research which have found specic microbial signatures connected with various conditions. These
strategies boost therapeutic efcacy by enabling accurate treatment adjustments and facilitating the
restoration of health through continuous feedback from the patient.
Another key issue requiring in- depth clinical investigation is in the area of antibiotic resistance
management. MRSA and MDR- TB are two deadly superbugs which pose serious health risks due to
their resistance to antibiotics. Resistance pattern analysis helps to discover the best ways to ght
against such types of bacteria through, for example, using combination medicines and new antibiotics, as well as alternative therapies like bacteriophage therapy. This insight also helps in the formulation of sustainable approaches which helps to resist the mutations of the germs and increase the
effectiveness of the treatment.
Herbal nanomedicine is a novel framework of therapy that aims to achieve maximum effectiveness of medical treatment with minimum side effects and increased accessibility of drugs to the
organism. Improvements in tumor markers or decreases in inammatory markers are two particular
patient responses to these drugs, which lead to drug delivery system optimization. To give just one
example: In the case of patients with cancers, any data collected could be used to improve the effectiveness of the particular treatment, for example, curcumin nanoparticles; with this feedback, they
will have more focus in lessening side effects. Therapy success evaluation takes into account all the
data from kinase assays, biomarker analysis, clinical observations, and PROs. Through medical
examination, we can gain immediate feedback on physical problems and disease markers; for example, curcumin nanoparticle treatment has been shown to reduce C- reactive protein (CRP). These
PROs can be collected, for example, through surveys or questionnaires, which include topics such
as symptom relief or quality of life. Biomarker analysis, like blood glucose monitoring in diabetes
treatment, helps to point out possible complications and also provides denite proof of any therapeutic effect. The increasing integration of articial intelligence and machine learning into clinical
result analysis will surely improve the future accuracy and efcacy of treatment methods, leading
the health of patients to be enhanced. Multivariate studies, which will be further developed with
advanced statistical software and tools, recognize positive outcome predictors and create prediction
models. These models permit the personalization of treatment plans, thereby ensuring that each
patient receives the most suitable and targeted care. To bring herbal nanomedicine onto the same
level as other medical elds, the methods of treatment should be continually improved through
research and evidence- based modications. This will result in an incremental method of clinical
result investigation, which provides the basis for the improvement of the treatment process.
19.4 STANDARDIZED TREATMENT PROCEDURES
The developments discussed above translate into a new era in health as herbal nanomedicines are
highly specic to a patient’s condition and personal needs. In this approach, nanoparticle engineering is used for the precision targeting of disease processes or specic organs (e.g., cancer theragnostics) to enhance treatment efcacy and minimize side effects. This promise of more effective
and personalized care, achieved by incorporating patient- specic data into their choices [30], will
improve the efcacy of therapy outcomes as well as relieving patients’ conditions, leading them
406 Herbal Pharmacopeia
towards compliance with prescribed treatments and transforming traditional herbal medicine into a
new branch of medical sciences, known as nanomedicines.
19.4.1 cuStomization for Specific ailmentS
One of the most signicant capabilities of herbal nanomedicine is its tailored formulation for specic disease conditions. Treatment efcacy can be further enhanced while unwanted effects are
minimized by ne- tuning the nanoparticles’ composition for targeted disease protocols or organs.
Important features of personalization include:
• Disease- specic nanoparticles: The design of nanoparticles with physicochemical characteristics that target the root cause of a disease
• Combination therapy: The combination of herbal nanoparticles with other potential medicinal entities to treat the complex disorders and offer synergistic effects.
• Personalized medicine: Personalized treatments tailored for the patient in order to optimize
results.
To give just one example: nanoparticles can be programmed to stick only on cancer cells and not in
healthy tissues, or they could dock with the sore joints of rheumatoid arthritis sufferers so that doses
of anti- inammatory medications are delivered directly to the required sites. It has also been seen
that in the case of rheumatoid arthritis, curcumin nanoparticles have shown a signicant decrease
in inammatory markers including C- reactive protein (CRP) and erythrocyte sedimentation rate
(ESR) [23]. This customization of the route increases tolerability and potency by avoiding systemic
inammation, while neutralizing a majority of gastrointestinal distresses experienced with higher
doses seen in traditional formats.
Likewise, nanoparticles from herbal extracts found in garlic and hawthorn can be direct to the
inner layers of blood vessels, thereby treating cardiovascular diseases [19]. It has also been shown
that phytochemical quercetin- mediated herbal nanoaggregates show great promise for use as nanodelivery vehicles of cardioprotective compounds to combat cardiovascular disorders. Again, quercetin nanoparticles have been shown to reduce oxidative stress (OS) and improve endothelial function
(EndoPF), which is an important method for controlling diseases such as hypertension and arterial
sclerosis [24]. This targeted approach is more efcient at reducing blood pressure and the absorption
of adjunct ingredients, thereby delivering increased diastolic blood pressure health when compared
with other treatments. In cancer therapy, the customization of herbal nanomedicines is especially
remarkable. This can be customized by the production of nanoparticles loaded with active anticancer herbal ingredients, which is especially effective in the case of conditions demanding targeted
actions. In the management of diabetes, for example, the use of nanoparticles enhances the delivery
of herbal extracts like kaempferol (KA) directly to pancreatic tissues, thereby bringing out the
intended therapeutic effects with a minimum of adverse systemic effects. Likewise, as observed in
several research works, targeted release applications for compounds from C. arborea extract portrayed higher efcacy toward the treatment of oxidative stress- related diabetes [27]. The plant alkaloid berberine, which is known for its anti- diabetic properties, often suffers from low bioavailability.
This issue is addressed by encapsulating berberine in nanoparticle form, enhancing absorption and
ensuring a sustained release of the active ingredient [24]. Clinical trials have demonstrated that berberine nanoparticle treatment can signicantly lower fasting blood glucose levels, improve insulin
sensitivity, and reduce HbA1c levels in patients.
Furthermore, herbal nanomedicine enables the production of nanoparticles that can penetrate the
blood–brain barrier, delivering active substances directly to the brain. This is promising for the treatment of neurodegenerative diseases like Alzheimer's disease. For example, ginkgo biloba extracts
encapsulated in nanoparticles have been shown to improve cognitive performance and preserve
neural integrity more effectively than conventional formulations [23]. As is clear from the ndings
Implementing Herbal Nanomedicine in Clinical Settings 407
outlined here, herbal nanomedicine is a powerful tool in modern healthcare, offering signicant
advancements in personalized medicine by precisely targeting therapies to the affected areas.
19.4.2 tailoring for inDiviDual patient neeDS
The above discussion has shown the importance of individualizing the treated preparations for the
patient’s condition in order to achieve efciency in the area of herbal nanomedicine. This approach
is more advantageous and promising, as it takes into account the specics of each patient. Tailoring
is an important aim because the decisions in clinical practice should be patient- specic (i.e. specic
to patients who enunciate their values, preferences, and health- related goals) and it is crucial to create methods in order to avoid (or at least reduce) the recognition of futility while increasing the ratio
of success.
If genetic data is combined with predictors, then better treatment options can be employed.
Precision medicine is a form of customized care regarding a particular patient, which is based on
clinical information and the patient’s genetic makeup and other factors. First, a comprehensive analysis of the patient’s heredity background, current diseases, and history is carried out. This knowledge also denes the process of choosing the right herbal nanoparticles together with the right
process of altering the pre- existing ones. During the course of the treatment, biomarkers, signs, and
symptoms are being monitored constantly in order to check for the safety and effectiveness of the
treatment. Adjustments are undertaken depending on the current conditions of the patient and/or the
emergence of new signs and symptoms.
The patient’s characteristics, including their age, weight or body surface area, genotype, metabolism, and renal/hepatic function, inuence the doses of some drugs in order to avoid side effects
while achieving the optimal therapeutic effect. In the case of gastric cancer, it may be appropriate to
employ combination therapy, with nano- encapsulated herbs being prescribed alongside other forms
of treatments in order to provide a multifaceted treatment plan to deal with such a chronic disease.
Once again, genetic markers, the stage of the disease, and metabolic characteristics could all be
taken into account in the process of nanoparticles creation.
Nanoparticles can be made to recognize specic tumour antigens or mutations that are diagnosed
in a patient’s cancer cells, especially in relation to the treatment of cancer as compared to routine
drugs. For instance, nanoparticle encapsulants of medications can be changed to incorporate sustained release therapeutic levels for various patients, taking into account individual speeds of metabolism and the stage of the disease. This enables the delivery of the drug to the required part in small
doses, which is a true strategy of adaptation.
The Individual Safety Assessments (ISAs) can play an important role in nding out the formulation and delivery system suitable for each patient, which will make the experience even safer for
treatment and increase the likelihood of better clinical outcomes. For example, nanoparticles with
herbal coatings can be designed to deliver drugs in response to blood glucose levels, increasing the
efcacy and minimizing incidents of hypoglycemia. In this regard, meeting the patient’s or client’s
needs and applying these complex technologies, it is possible to optimize the choice and usage of
herbal extract- based replacement therapy (HERT) while enhancing the health status (HS) satisfaction with the applied herbal medicine and, simultaneously, guaranteeing the safety and effectiveness
of the herbal nanomedicine.
19.5 ADVANTAGES OF HERBAL NANOMEDICINE IN CLINICAL SETTINGS
Herbal nanomedicines signicantly increase patient adherence, minimize adverse effects, and enhance
therapeutic efcacy by improving bioavailability and targeting capabilities. Because nanoparticles
may mitigate the drawbacks of traditional herbal formulations, such as poor solubility and delayed
action, more patient- friendly and successful therapies are now possible. This section looks at how
these developments lead to improved clinical results and more effective application of herbal remedies.
408 Herbal Pharmacopeia
19.5.1 increaSeD patient aDHerence
It has been shown that the patient compliance is far better in case of the herbal nanomedicine than
is the case with synthetic drugs. Similarly,, herbal nanoparticles have the capability to act more rapidly and effectively than normal herbal extracts due to disadvantages associated with capsules and
tablets such as low solubility and slow rate of dissolution. This can enhance patients’ compliance
with the recommended treatments and overall healthcare outcomes. Whereas a number of complications surface with traditional herbal therapy, the major handicap lies in achieving compliance from
the patients due to their large size, the unpleasant bad taste, and their often frequent administration.
These problems are solved by herbal nanomedicine as this increases the stability and bioavailability of the herbal constituents; it therefore reduces the frequency of administration per treatment.
As a result, active herbal components encapsulated in nanoparticles can enhance patient compliance due to the elimination of some of the downsides associated with traditional herbal medicine.
This patient- specic approach makes it easier to individualize the therapies to t every individual,
thereby enhancing the yields of herbal nanomedicines [20, 22, 28].
19.5.2 reDuceD SiDe effectS
Traditional remedies are deemed to have fewer side effects than synthetic ones. Nanotechnology
improves this advantage by allowing the practice of personalized medicine, decreasing side effects,
and assessing and avoiding potentially fatal consequences. This can be benecial to patients as it
enhances comfort and therefore improves their quality of life. Herbal nanomedicine solves these
problems due to the targeted release and delivery of therapeutic agent’s desired site, minimum circulation in the system, and thus minimal doses. These nanoparticles can be made in such a way
that they release their contents only in the intended area of the body, thus reducing harm to other
organs. For instance, berberine nanoparticles contrasted positively with non- nano berberine in diabetic regulation with fewer gastrointestinal side effects [19, 20]. It removes the possibility of side
reactions, hence making treatments more tolerable and safer and, thus, improving patient adherence.
Nanotechnology in the drug delivery system is quite effective in the precise targeting of the location
where the drug has to be delivered so that the incidence of side effects in the herbal medicinal drugs
can be avoided as much as possible. For instance, silymarin- loaded liposomes for liver disorders
exhibit a high level of hepatoprotective benets with a minimal side effect level on the gastrointestinal tract (GIT) compared to other regular oral formulations [20, 28]. Nanotechnology has a capacity
to reduce the chances of side effects since it regulates the rate of drug delivery, thereby reducing the
chances of a sudden buildup of medication concentration in the patient’s body. Herbal drugs and
remedies have enhancing quality through the application of nanotechnology and thus the issues,
such as solubility, stability, and bioavailability issues are sorted out. This allows for smaller amounts
of the active ingredients to be packed into nanoparticles and nano- emulsions, thus allowing for the
patient to take smaller doses at wider intervals and yet for the medicine to retain its effectiveness.
For instance, curcumin- loaded nanoparticles can be given to the patients less frequently for chronic
diseases such as diabetes and heart diseases, yet the patients will adhere to the treatment schedules.
Among the advantages are that, occasionally, dosing regimens require the patients to take several
doses in a day; however, with these preparative, dosing regimens are simplied resulting the reduced
chances of patient noncompliance. The use of nanotechnology also enables the enhancement of the
strength of therapeutic effects and lessening of undesirable effects.
19.5.3 improveD efficacy
The encapsulation of herbals in nanoparticles improves the solubility and bioavailability of active
ingredients, enhancing therapeutic efciency. Nanoparticles can also deliver drugs directly to specic
tissues or organs, increasing the concentration of active ingredients at the site of action, and resulting
Implementing Herbal Nanomedicine in Clinical Settings 409
in more potent and efcacious therapies. Herbal nanomedicine is known for its increased effectiveness. The higher permeability of cellular units provided by nanoscale particles facilitates greater
absorption and penetration at a cellular level, enhancing the overall therapeutic efcacy of herbal
compounds. For example, ginseng extracts encapsulated in nanoparticles have shown improved bioavailability and therapeutic efcacy in reducing fatigue and enhancing cognitive abilities [27]. This
precision is particularly important in treating diseases such as cancer or antibiotic- resistant infections, requiring high accuracy and powerful interventions. Many biologically active constituents
in herbal extracts, such as terpenoids, tannins, and avonoids, have large molecular sizes and poor
membrane permeability, leading to low absorption across cell membranes. However, these components are also highly water- soluble. Nanoparticles eliminate these barriers, enhancing the delivery of
therapeutic agents. In the case of ischemic cerebral injury, breviscapine encapsulated in multivesicular liposomes shows prolonged blood circulation and continued release, thereby improving therapeutic outcomes [23]. Nanotechnology provides better solubility, stability, and targeted delivery of
conventional herbal treatments, enhancing their therapeutic efcacy with lower dose requirements.
Nanomedicine offers a potential tool for delivering drugs more effectively, enabling better uptake
and utilization of plant components, and broadening the applicability of disease management without deleterious side effects. These nanoparticles have shown greater anti- cancer efcacy in tumor
growth inhibition and apoptosis induction when compared with conventional curcumin formulations
[20]. Moreover, the controlled release properties of nanoparticles maintain therapeutic levels over
the long term, ensuring sustained efcacy without drug resistance during chronic treatments.
19.6 THE FUTURE OF HERBAL NANOMEDICINE IN CLINICAL PRACTICE
Herbal nanomedicine is the new evolution in healthcare, and it has immense possibilities for revolutionizing clinical practice. The continuous improvement of nanotechnology yields new- generation
herbal nanoparticle compositions that are even more advanced and well- suited. This includes the synthesis of nanoparticles with biocompatible properties, stimuli- responsive release proles, and higher
targeting capabilities. Herbal nanomedicine can be personalized for each individual by incorporating
genomics, proteomics, and metabolomics, thereby making it more effective with fewer side effects.
Combining antipathogenic drugs and herbal nanoparticles will provide insights into synergistic
drug interactions, offering novel opportunities to combat complex diseases. Mixing both could
improve patient outcomes and lessen the reliance on synthetic drugs. There need to be strict regulatory guidelines for the development and therapeutic application of herbal nanomedicine. In a health
system that strongly encourages innovation for the benet of producers rather than all patients on
grounds of safety and efcacy, stringent measures must regulate stem cell ‘customization.’
Herbal nanoparticle guidelines should be developed through innovatively advanced effective,
safe, and quality measures supported by standard regulatory frameworks with uniform testing protocols. The main thrust of future endeavors should be to set standard operating procedures for the
clinical application of herbal nanomedicine, with a full compilation of preclinical studies, side
effects, and follow- up. Meeting these requirements and developing a greater degree of consumer
condence in herbal nanomedicine demands the amalgamation of researchers, physicians, and regulatory authorities.
International collaboration between researchers, clinicians, and regulatory authorities is needed
to catalyze the faster development and acceptance of herbal nanomedicine. The integration of
research ndings into clinical practice can also be assisted by sharing both knowledge and resources.
To facilitate the adoption of herbal nanomedicine by health systems, public education is paramount.
This will require educational initiatives and patient empowerment programmes to foster the adoption of these therapies. The transformation of these nanoparticles from bench to bedside, requiring
additional research and clinical trials currently in progress, may move the management of chronic/
co- morbidities in a completely different direction altogether, leading to better patient outcomes on
Planet Earth.

20.1 HERBAL NANOMEDICINES: A BRIEF OVERVIEW
Herbal medicines are plant- derived valuable and renewable bioactives that offer potentially immense
therapeutic benets. They have a long well- documented history of traditional uses in Indian,
Chinese, and other complementary and alternative systems of medicine. Folklore medicine and ethnic preparations constitute the basic foundation upon which modern- day herbal formulations have
been developed. They have considerable potential in the management of several chronic diseases,
cancers and the amelioration of critical life- threatening conditions. In many developing nations
across the globe, a signicant proportion of the population continues to depend on traditional herbbased medicinal systems for the relief and healing of disease symptoms. Herbal formulations are
slowly beginning to gain popularity over the past few decades, even in the Western world, which has
traditionally viewed such treatments as unscientic. Since the herbal preparations are composed of
several characterized and uncharacterized active principles, they can attack a disease from different
angles and thus prove to be highly benecial over conventional allopathic systems of medicine (Ai
ei al., 2024; Anand etal., 2024; Jalili etal., 2023; Mansingh etal., 2023; Subbiah etal., 2019).
Despite their popularity and health benets, the realm of herbal formulation- based therapeutic strategies is frequently marred by several drawbacks during the initial stages of formulation development
These include the presence of pharmacophores of complex chemical structures and stereochemistry,
the presence of unidentied and un- characterized therapeutically active moieties, suboptimal physicochemical and pharmacokinetic attributes, the risk of inter- batch variation in the quality of extracts and
content of active principles, and inadvertent and unavoidable exposure to living and non- living
412
Safety Proles and Potential Toxicological Concerns of Herbal Nanomedicine 413
contaminants and pollutants from soil, water, and air and the entry of impurities during cultivation and
harvesting (Anand etal., 2024; Mansingh etal., 2023; Subbiah etal., 2019).
Nanotechnology is envisaged as a transformative platform to address the pitfalls of achieving
desired therapeutic action from herbal formulations. The revolutionary approach has opened promising avenues and unlocked the doors to improving the bioavailability, efcacy, and efciency of
herbal formulations, culminating in the emergence of herbal nanomedicines. The integration of
herbal medicine with nanotechnology is poised to expand the landscape of traditional practices with
herbs and herb- based formulations, and has been instrumental in addressing the limitations and
harnessing the potentials of these valuable drug resources. Herbal nanomedicine development is
continuously expanding, advancing into domains where conventional allopathic therapies have
failed and evolving as a stepping stone to unforeseen advances in future healthcare (Alemi etal.,
2024; Jalili etal., 2023; Kad etal., 2022; Khan etal., 2021; Kumar etal., 2021).
Herbal nano- formulations have been developed using a multitude of phytochemicals and

nanotechnology in overcoming the hurdles and improving the therapeutic outcomes of herbal
medicines. Nano- formulations have also been fabricated with Aloe vera extract and neem leaf
extract (Alti etal., 2020; Subbiah etal., 2019).
It is interesting to mention that the nanovehicles or nanocarriers that have been developed by
research scientists across the world for the delivery of herbal medicines or extracts or phytoconstituents can be broadly categorized as engineered or manufactured soft and hard nanoparticles(NPs).
They have been fabricated articially from biodegradable and non- biodegradable organic and inorganic constituents such as polymers, lipids, metals, metallic oxides, carbon in contrast to the ones
that are formed naturally in living systems or are formed accidentally in the environment. The chemical component from which the nanomaterials are being constructed may be obtained from either
natural or synthetic sources. Most of the nano- formulations developed to date are rst- generation or
second- generation NPs designed to improve the functionalities of the bulk counterparts and are
involved actively in the process (Li etal., 2022; Anwar etal., 2021; Ray etal., 2021; Gupta etal.,
2019; Qiu etal., 2018).
The chapter aims to offer a comprehensive analysis of the safety and toxicity concerns associated with nanomaterials used as carriers in the delivery of herbal medicines. It seeks to critically
assess how nanomaterial attributes rather than their cargo contribute to the toxic and adverse outcomes, to investigate the impact of the engineered nanomaterials on the biotic and abiotic components of the ecosystem of which the end- user is a part. Individuals involved in manufacturing and
