Abstract
Stress testing is defined as the stability testing of drug substances and drug products under conditions exceeding those used for accelerated testing. Stress testing provides information about degradation mechanisms and potential degradation products. The purpose of this work is to study the stability of substances of herbal origin by stress-testing. Various substances present in herbals and herbal medical products indicated in pharmacopoeias were taken into research. Chlorogenic acid in qualitative analysis of Urticae folia; ellagic acid - Alni glutinosae folia, caffeic acid - Taraxaci officinalis radices and Phaseoli vulgaris valvae fructus; arbutin – Vaccinii vitis-idaeae folia and Uvae ursi foliа, 20-hydroxyecdisone - Rhapontici carthamoides rhizomata cum radicibus and folia, glaucine – the main alkaloids of Glaucium flavum herba were used. The next conditions of stress-testing were chosen: hydrolysis in neutral (purified water), acid (0.01 M HCl) and alkaline (0.01 M NaOH) hydrolysis, treatment with 0.05 M aqueous solutions of ions of Cu2+ and Fe2+ for 14 days, and 0.1 and 2 % hydrogen peroxide for 24 h. The destruction of substances less than 15% during the period of storage was regarded as satisfactory result. It has been established that all investigated substances were stable in solutions of hydrogen peroxide and in purified water. Ellagic, chlorogenic and caffeic acids are unstable in solutions of alkaline, acids and metal ions. 20-Hydroxyecdysone was destructed in alkaline solution. These data can be used further in manufacturing processes or for selection of packing methods of medicinal herbals.

Abstract
The worldwide use of herbal medicines has been increased over a past few decades. One or the other form of herbal medicine are used by around 80% of population atleast once in their life time. Herbal medicines have promising potential with respect to their efficacy is concerned but the major problem is that, most of the herbal products of interest remain untested, its monitoring is way far behind, and the knowledge of their pharmacokinetics and pharmacodynamics are poorly understood. So safety regarding the usage of these products has become a fundamental principle. WHO guidelines specifies that ADRs reported with the use of herbal products are mainly because of lack in quality, adulteration, inappropriate usage or due to the presence of pathogenic microorganisms. Also poor regulatory policies, improper quality control measures and unrestrained distribution of these products were suggested by WHO as additional factors for increase in the incidence of ADRs. Presence of multiple ingredients in the herbal products and its combination with conventional medications makes it difficult to identify the exact agent causing the adverse reaction; added to that, most of these products enter into the market without undergoing any clinical trials. Because of uninterrupted increase in use of herbal product there is a need to strengthen the regulatory system for quality and control of herbal medicine. Even though monitoring of these products has been included in the national pharmacovigilance program, there is a need to raise the awareness among the doctors and para medical staffs regarding the ADR reporting of these products. Hence the post marketing Pharmacovigilance plays a crucial role in monitoring the safety and efficacy of these herbal products and its accomplishment depends on awareness of National Pharmacovigilance Program among health care professionals
