(Faculty of Science, University of Kelaniya Sri Lanka, 2022) Nishan, S. P. A. S.; Wickramasinghe, M. R. M.
Ayurveda is an ancient system of medicine that focuses on the preventive or prophylactic and curative aspects of health. ‘Ayurvastra’ is a combination of the words ‘Ayuh’ and ‘Vastra’. Ayuh refers to long life and Vastra means clothing. The process of developing medicinally treated fabric involving Ayurveda to preserve health in an eco-friendly manner is a great way of adopting a healthy life. Ayurveda has endless scope to capture the global market for Ayurveda products. Foreign currency earnings by Ayurveda in 2020 was US$ 4571.7 million. The objectives of this project were to develop a novel preparation of Ayuvastra treated by herbal raw materials with natural dyeing process to provide human friendly textiles to preserve natural health of people, to introduce eco-friendly manufacturing process of herbal extracts treated clothes for modern textile industry instead of chemical dyeing process and to enhance the trend of use of herbal treated fabrics in Sri Lankan textile industry targeting with international fabric market. In this study, the pharmaceutical analysis of selected herbal raw materials (Aralu- Terminalia chebula, Neem- Azadirachta indica, Turmeric- Curcuma longa, Lime-, Citrus aurantifolia) were reviewed from previous research articles. Reviewed pharmaceutical analysis of bioactive ingredients of selected plants’ raw materials showed anti- septic, anti-allergic, antifungal, anti-inflammatory, antimicrobial, and immunomodulatory in antioxidant properties. The sample was prepared following several cryogenic procedures. Selected cotton graige fabric was bleached with lime juice and the gumming process was conducted by immersion in Aralu decoction, then soaked into filtered Neem and Turmeric decoction, and heated under mild flame while being stirred. The medicinally treated cloth was washed by diluted decoction to remove additional colour and dried in air. As per reviewed data, it can be concluded that Ayurvastra can be used for skin infections, eczema, hypertension, asthma, diabetes and a broad range of diseases and it is based on the therapeutic effect of used herbal raw materials for manufacturing. Further, pharmaceutical analysis will be conducted to evaluate therapeutic efficacy of medicinally treated fabrics.
A literature review on the antimutagenic effect of Thriphala wsr to Rasayana therapy

Plants have been a prime source of highly effective medicinal preparations for the treatment of many forms of cancer. Mutations are capable of altering the genome, having an immense potency to create defects in the human body. They are reflected as hereditary disorders or cancer. At present, cancer has become a leading cause of death worldwide accounting for nearly 10 million deaths according to World Health Organization Statistics 2020. Mutagens play a key role in cancer whereas antimutagens counteract with the action of mutagens thereby curing cancer. Bestowing the normal functions and equilibrium of anatomical structure of the Dosha Dhatu (cells and tissues) is one of the major qualities of Rasayana (rejuvenative) therapy, which is one of the eight branches of Ayurveda. Rasayana therapy is defined as preventing senility by stabilizing youthfulness, eliminating disease and promoting longevity. Thriphala being a composition of Terminalia chebula, Terminalia bellerica and Phylanthus emblica is a frequently used medicine in Rasayana Therapy among its many other therapeutic uses. The main objective of this study was to review the relationship between the anti-mutagenic effects of Thriphala with special reference to Rasayana Therapy. This study was carried out as a review study and data were collected from published research articles and authentic Ayurveda texts. Among Pharmacodynamic properties described in authentic texts, Kashaya Rasa, Laghu, Ruksha Guna, Ushna Veerya and Madhura Vipaka were the most prominent. According to reviewed data of previously published research articles, Thriphala contains bioactive compounds such as flavonoids, saponins, anthraquinones, amino acids, fatty acids and various carbohydrates. Among them tannins, gallic acids, ascorbic acid are the major constituents mentioned to be accountable for immunomodulatory action which is achieved by inhibiting, activation of mutagens, blocking and anti-oxidation action claimed to be as anti-mutagenic. Considering the relationship between Rasayana and antimutagenic effect, Agni promoting action which is one of the predominant pharmacological attributes of Thriphala, is not only confined to Jatharagni (Digestive fire) and Sapthadhathu Agni (Tissue level metabolism) but also to the Panchabhutha Agni (Cellular level metabolism). Hence molecular targeted therapeutics are more efficient in destroying cancer cells and eradicating them at molecular levels. Therefore, the process of cell division takes place at its optimal state without any interruption, where Panchabutagni eliminates Aama at the cellular level, which can be correlated with mutagens. This process enhances the immunity of cells and tissues by imparting resistance against cancer. Hence, using Thriphala on a regular basis is proven to be beneficial in Ayurveda practice. Further pharmaceutical analysis of individual ingredients and compounds Thripala and clinical studies will be carried out to evaluate the efficacy of Thripala in therapeutic effect of Rasayana in cancer therapy to scientifically validate the results.
