2. Botanical Variation
 Natural variations in plant species can lead to differences in the chemical
composition of raw materials.
 Biotic and abiotic factors such as geographical location, climatic conditions,
plant habitat, season, stage of growth, soil conditions can affect the quality of
herbs.

3. Adulteration
 Adulteration may occur due to intentional mixing with lower-cost substitutes
for more profit or sometimes in conditions of scarcity of right material.
 Unintentional contamination during harvesting, processing, or storage.
 Common practice of adulteration and substitution which resulted in inferior-
quality of the finished products.

4. Standardization of Herbal Extracts
Standardizing the concentration of active compounds in herbal
extracts is difficult due to the variability in plant sources.
Establishing consistent potency is crucial for ensuring the efficacy
and safety of Ayurvedic formulations.

5. Heavy Metal and Pesticide Contamination
Plants can accumulate heavy metals and pesticides from the soil,
water, and air.
Controlling and monitoring the levels of these contaminants in
Ayurvedic raw materials is crucial to ensuring the safety of the
products.

6. Microbial Contamination
Herbal materials can be prone to microbial contamination during
cultivation, harvesting, and processing.
Implementing appropriate measures to control microbial
contamination without compromising the integrity of the herbs
is a significant challenge.

7. Lack of Analytical Techniques
Traditional Ayurvedic medicines may not have well-established
analytical methods for quality assessment.
Developing and validating robust analytical techniques for the
identification and quantification of active compounds is essential.

8. Regulatory Compliance
Meeting regulatory requirements for quality control can be
challenging, especially when there is a lack of harmonization in
standards for herbal products across different countries.
Compliance with Good Manufacturing Practices (GMP) is
crucial.

9. Limited Research on Ayurvedic Formulations
Limited scientific research on Ayurvedic formulations and their
efficacy can hinder the establishment of quality standards.
Collaborations between traditional knowledge and modern
scientific research are essential to bridge this gap.

SN Challenges Remedies
1 Botanical
variation
Encourage and support farmers in adopting good agricultural
practice.
Provide training and resources on sustainable cultivation methods
and proper harvesting techniques.
2 Adulteration Sourcing from reputable suppliers, Quality control and testing at
various stages of supply chair. Conduct Supplier audits at regularly
3 Standardization
of Herbal Extracts
Sourcing of standard quality raw materials. Establish detailed quality
testing.
4 Heavy Metal and
Pesticide
Good Agricultural practises. Avoid harvesting from polluted areas.
Post-Harvest Processing (Cleaning & Washing). Pesticide selection -
Use of organic pesticides
5 Microbial
Contamination
Good Agricultural Practices (GAP). Proper Drying and Storage. Use
of Natural Antimicrobials.
6 Lack of Analytical
Techniques
Invest in Research and Development. Adopt Modern Analytical
Methods (HPLC, HPTLC, GC-MS, LC-MS). Collaborate with Regulatory
Authorities
