Background and Objective: Systematic study of the folklore knowledge on herbal drug contributes to its conservation and preservation. Documentation of drugs in Ayurveda is based on the five principles called Rasa Panchaka (5 Ayurvedic principles of drug action). Alstonia venenata R. Br is a small tree belonging to Apocynaceae family. Its stem bark is used by tribes in fever, epilepsy and as anti-venom in snake bites. The aim of this study is to determine the Rasa Panchaka (5 Ayurvedic principles of drug action) of Al-stonia venenata R. Br.
Methods: Detailed review of the trial drug was carried out. Rasa (taste) was determined by using direct per-ception method on 30 healthy volunteers. Veerya (potency) was determined by assessing the exothermic and endothermic reaction of the drug in water. Vipaka (taste after digestion), Guna (properties) and Prab-hava (specific action) were assessed by experimental study of the drug on 12 Wister Albino rats.
Result and Conclusion: After the study Rasa panchaka (5 Ayurvedic principles of drug action) of the test drug was accessed as Tikta (bitter) Rasa (taste), Laghu (light) Rooksha (dry) Guna (property), Sheetha (cold) Veerya (potency)and Katu (pungent) Vipaka (taste after digestion).
A wound is a break in the integrity of the skin or tissues often which may be associated with disruption of the structure and function. Globally, the magnitude of acute wounds as a healthcare problem is sharply rising mainly due to industrialization. There is still a need to revisit the ancient healing methods by using traditional medicine aiming to discover a wound healing drug with better protection, rapid granulation changes, least side effects, good bio-availability and low cost. A folk medicinal plant Humboldtia vahliana Wight. belongs to the family Fabaceae, is a medium sized tree with rough, dark brown bark mottled with white. Its stem bark is used for wound healing among the tribes. Aims and objectives: The study aims to evaluate the in-vivo wound healing action of Humboldtia vahliana Wight. through excision and incision animal wound models. Methodology: 36 male Wistar albino rats weighing 150-250gm. were selected and made into 3 groups each for both incision and excision wounds, i.e., control, standard and trial group -each containing 6 rats. The trial drug Humboldtia vahliana Wight. was applied over the wound area in the form of ‘Kalka’. In excision wound model, percentage of wound contraction was the parameter for the study and was achieved by using Planimetry. In incision wound model, tensile strength was the parameter and was achieved by Local Tensiometer. Results: In case of both Incision as well as Excision wound contraction study, the data shows a statistically non-significant increase in percentage wound contraction of Trial group when compared to Control and Standard groups. Interpretation and Conclusion: The stem bark of Humboldtia vahliana Wight. showed better wound healing action in Wistar albino rats when percentage of efficacy or mean values were compared
Apama siliquosa Lam is a folklore drug which is used to treat diarrhoea. It is locally known as Chakranike. The root of the drug is said to be effective in treating diarrhoea, cholera. The complete description of the drug is not available in the texts of Ayurveda. In this study an attempt is made scientifically to identify the drug Apama siliquosa.Lam. Pharmacognostical and phytochemical study of the drug is done to standardize the plant. The macroscopic as well as microscopic features of the plant is observed. Physico-chemical parameters such as loss on drying, total ash, acid insoluble ash, alcohol soluble extract, water soluble extract was assessed. Preliminary phytochemical screening was conducted by chloroform, benzene, methanol and petroleum ether extracts of the drug A. siliquosa. Lam. It revealed the presence of alkaloids, carbohydrates and glycosides. TLC, HPTLC plates of the drug were also developed and Rf value, color of the spot, densitometry scan was recorded.
Background and objective: In India Medicinal plants have a wide range of uses in folk medical practice. An- drographis macrobotrys Nees. belongs to Acanthaceae family is found in South India and Srilanka. It is in folk use by tribes in Kerala to treat muscle pain, snakebite, fever, and jaundice. The present research work aims to evaluate test drugs for their analgesic action. Methods: The detailed review of the test drug and disease Pain has been carried out. An animal experimental study has been carried out to assess the analgesic activity of the drug by acetic acid- induced writhing movement in Swiss albino mice and Eddy’s hot plate method in Wistar albino rats. Results and conclusion: The test drug showed analgesic action with Swarasa of leaves and Kashaya of the whole plant. The drug was found to have both peripheral and central analgesic action.
Keywords: Andrographis macrobotrys Nees., Acanthaceae, folk medicinal plant, Analgesic action
