Histochemical Investigation Of Two Plant Species Valued As Medhya Rasayanas
We chose two different taxa used in folk medicine to determine their histochemical investigation: lessThan i greaterThan Bacopa monniri lessThan /i greaterThan Pennell. and lessThan i greaterThan Centella asiatica lessThan /i greaterThan Linn lessThan i greaterThan . lessThan /i greaterThan Both the plants widely known as Brahmi are considered as 'Medhya rasayanas' in Ayurveda meaning brain tonic. However, these plants are distinctly different. The name Brahmi, Jala-brahmi or water-brahmi is assigned to lessThan i greaterThan Bacopa monnieri lessThan /i greaterThan whereas lessThan i greaterThan ' lessThan /i greaterThan mandukaparni', often confused with Brahmi, refers to lessThan i greaterThan Centella asiatica lessThan /i greaterThan . A detailed histochemical investigation of leaf and stem of both the drugs was carried out. In general, these plants are used in folk medicine in the treatment as medhya rasayanas or 'mental rejuvenatives. Brahmi is used to treat specific mental disorders such as insanity and epilepsy, while mandukaparni is a general rejuvenative tonic which improves mental health. Brahmi promotes fertility and sustains implantation of the embryo in the uterus, while mandukaparni tends to reject the embryo. For histochemical studies, the free hand sections of leaves and stem were taken and treated with the respective reagent in localize components, lessThan i greaterThan viz lessThan /i greaterThan . starch, protein, tannin, saponin, fat, Sugar, glucosides and alkaloids in the tissues.
