Habitat: Throughout India as a weed.
English: Horse-purslane, Hogweed.Ayurvedic: Rakta-punarnavaa, Punarnavaa, Katthilla, Shophaghni, Shothaghni. Varshaabhu (also equated with Trianthema portu- lacastrum Linn., which exhibits anti-inflammatory, antipyretic and analgesic activity).Unani: Itsit, Bishkhaparaa.Siddha/Tamil: Mookkirattai.Folk: Gadaha-purnaa.Action: Diuretic, anti-inflammatory, antiarthritic, spasmolytic, antibacterial (used for inflammatory renal diseases, nephrotic syndrome, in cases of ascites resulting from early cirrhosis of liver and chronic peritonitis, dropsy associated with chronic Bright's diseases, for serum uric acid levels). Root—anticon- vulsant, analgesic, expectorant, CNS depressant, laxative, diuretic, abortifacient.
Key application: As diuretic, hepatoprotective. (Indian Herbal Pharmacopoeia.)B. repanda, synonym B. chinensis Linn., roots exhibited antihepatotox- ic activity against carbon tetrachloride galactosamine-and paracetamol- induced intoxication in rats. Powdered root gave encouraging results in spermatorrhoea and leucorrhoea.The chloroform and methanolic extracts of the roots and aerial parts of B. diffusa also exhibited antihepatotox- ic activity against carbon tetrachloride- induced intoxication in rats.Punarnavaa is official in IP as a diuretic. The diuretic action of the drug is attributed to the presence of xanthone, beta-ecdysone. Flavonoid, arbinofura- noside, present in the drug, was found to lower serum uric acid in experimental animals, as also in humans.Punarnavaa has been reported to increase serum protein level and reduce urinary protein extraction in clinical trials in patients suffering with nephrotic syndrome. The activity is attributed to the presence of rotenoids in various parts of the plant.An antifibrinolytic agent, punar- navoside, has been found to stop IUCD-induced bleeding in monkeys. The drug contains quinolizidine alkaloids.Dosage: Whole plant—20-30 g for decoction (API Vol. I); root—1-3 g powder; 10-20 ml fresh juice. (API Vol. III.)... boerhavia diffusaHabitat: The plains from Punjab to Bihar, extending southwards to Karnataka.
Ayurvedic: Varshaabhu (related species).Action: Plant—astringent in stomach diseases, deobstruent, abortifacient.
The root and stems contain hentri- acontane, hentriacontanol, beta-sitos- terol glucoside, stigmasterol glucoside and nonacos-1-en-4-one.... trianthema govindiaHabitat: South India, Gujarat, Rajasthan, Uttar Pradesh and Haryana.
Ayurvedic: Varshaabhu (related species).Siddha/Tamil: Vellai Sharunnai.Folk: Bisakhaparaa.Action: Root—deobstruent; used for asthma, hepatitis and amenorrhoea. The root, leaf and stem gave positive test for alkaloid. The plant is a good source of zinc (1.077 ± 0.188) and copper (0.416 ± 0.057) mg/100 g.
Synonym: T. monogyna Linn.Family: Aizoaceae.Habitat: Cultivated fields and wastelands.
English: Horse Purslane.Ayurvedic: Varshaabhu, Vrshchira, Vishakharparikaa, Shilaatikaa, Shothaghni, Kshdra. Wrongly equated with Shveta-punarnavaa or Rakta-punarnavaa. Varshaabhu and Punarnavaa are two different herbs. T. portulacastrum is a rainy season annual. Rakta-punarnavaa is equated with Boerhavia diffusa, Shveta-punarnavaa with white- flowered species, B. erecta L. (B. punarnava).Unani: Biskhaparaa.Siddha: Sharunai.Folk: Pathari, Bisakhaparaa.Action: Root—antipyretic, analgesic, spasmolytic, deobstruent, cathartic, anti-inflammatory.
Leaves—diuretic; used in oedema and dropsy. A decoction of the herb is used as an antidote to alcoholic poison.The Ayurvedic Pharmacopoeia ofIn- dia recommends the dried root in diseases of the liver and spleen, anaemia and oedema.Ethanolic extract of the aerial parts exhibited hepatoprotective activity in CCl4-induced intoxication in rats. The acetone-insoluble fraction of the extract is responsible for the activity.The red and white flowers contain an alkaloid trianthemine, also punaranavine. The plant also gave ecdysterone (0.01 g/kg), a potential chemosterilant; nicotinic acid and ascorbic acid. The plant is rich in phosphorus and iron but poor in calcium.The high content of oxalate affects the assimilation of calcium. Carotene (2.3 mg/100 g) has also been reported.Trianthema sp. are used as adulterant of the roots of Boerhavia diffusa.Dosage: Root—2-5 g powder. (API, Vol. IV.)... trianthema portulacastrumHabitat: The sub-Himalayas tract from Punjab to Nepal, Sikkim, Bhutan, Assam, Western Ghats and the Andamans.
English: Rauvolfia root, Serpentina Root, Indian Snakeroot.Ayurvedic: Sarpagandhaa of Ayurvedic texts was not the Sarpagandhaa of modern medicine. (Sarpagandhaa was equated with Naakuli, Sarpach- hatrikaa and Varshaasu Chha- trikaaraa. Sarpagandhaa and Sarpasugandhaa were synonyms of Naakuli.)Folk: Chhotaa Chaand.Action: Root—decoction is employed to increase uterine contractions and for expulsion of foetus in difficult cases. The total alkaloidal extract of the root induces bradycardia, hypotension, sedation. It finds application in hypochondria, neuropsychi- atric disorders, psychosis and schizophrenia.
Key application: In mild, essential hypertension (borderline hypertension, especially with elevated tension of the sympathetic nervous system, for example, sinus tachycardia, anxiety, tension and psychomotor irritation, when dietetic measures alone are not sufficient. (German Commission E.)(Average daily dose: 600 mg drug corresponding to 6 mg total alkaloid.) Treatment is usually administered with a diuretic to prevent fluid retention which may develop if Rauvolfia root is given alone. (WHO.) Contraindicated in depression, bleeding disorders, gastric and duodenal ulcers. (Sharon M. Herr.) Also contraindicated in pregnancy, since it has both teratogenic and abortifacient potential. (Francis Brinker.)The root and root bark are rich in alkaloids, the most important being reserpine, others, around 30, which include ajmaline, ajmalicine (raubasine), ajmalicine, yohimbine, coryanthine, iso-ajmaline, neo-ajmaline, papaver- ine, raubasine, rauwolscine, rescin- namine, reserpine, sarpagine, serpentine, serpentinine, serpinine and de- serpidine.Reserpine is hypotensive and tranquilizer, used for certain forms of mental disorders. Ajmalicine (raubasine) and rescinnamine are also hypoten- sive and tranquilizer. Deserpidine is sedative, as well as hypotensive. Aj- maline exhibits antiarrhythmic activity.A number of Rauvolfia species are found in India: R. beddomei Hook. f.; R. densiflora Benth ex Hook. f. (Himalayas, Khasi and Aka Hills; Western and Eastern Ghats); R. micrantha Hook. f; known as Malabar Rauvolfia, (Kerala, up to an altitude of 300 m)The roots of R. beddomei contain ajmalicine, sarpagine and serpentine, but no reserpine. R. densiflora yielded 0.51% of total alkaloids (reserpine 0.01%). R. micrantha gave ajmalicine, raunamine, reserpiline, sarpagine, neosarpagine, in addition to reserpine.(In classical Ayurvedic texts, Nakuli and Gandha-naakuli were included in compound formulations for mental diseases.)... rauvolfia serpentina
