Swertia chirata
Swertia chirata/Drug Interactions:
AnthelminticsAnthelmintics: Extracts of Swertia chirata root exhibited anthelmintic activity in vitro and in animal studies on Haemonchus contortus, Pheretima posthuma, Haemonchus contortus, and the earthworm Pheretima postuma (22; 15; 23). Extracts administered to sheep naturally infected with mixed species of gastrointestinal nematodes showed a significant reduction in egg per gram of feces. AntibioticsAntibiotics: Extracts of Swertia chirata showed inhibitory activity against various Gram-positive and Gram-negative bacteria (6). The antibacterial activity was comparable to that of gentamicin.AntidiabeticsAntidiabetics: Animal studies have shown hypoglycemic activity using extracts from Swertia chirata (oral administration of 250mg/kg) (20). The extract also prolonged the blood sugar-lowering effect of tolbutamide when orally administered separately in animals (21). Antileishmanial drugsAntileishmanial drugs: Extracts derived from Swertia chirata were found to exhibit antileishmanial activity in animal studies (24; 25; 14). AntineoplasticsAntineoplastics: Swertia chirata has been reported to possess anticancer properties against various types of malignant and benign tumors (26). One extract containing amarogentin exhibited antiproliferative and proapoptotic activities in a mouse skin carcinogenesis model (8). The extract also exerted toxicity on the cellular growth of rat Reuber hepatoma cell line H4IIEC3/G- (4). Antiobesity agentsAntiobesity agents: Extracts of Swertia chirata inhibited pancreatic lipase activity (27).Antiulcer agentsAntiulcer agents: In animal research, extract of Swertia chirata significantly reduced the intensity of gastric mucosal damage induced by indomethacin and necrotizing agents (10). It produced a significant decrease in gastric secretion in pylorus-ligated rats. Pretreatment of rats with the extract significantly prevented ethanol-induced gastric wall mucus depletion and restored the nonprotein sulfhydryl (NP-SH) content in the glandular stomachs, indicating that the extract may be useful in treating gastric ulcers. AntiviralsAntivirals: Swertia chirata extracts showed antiviral properties against Herpes simplex virus (HSV) type 1 (7). Infected cell cultures treated with such an extract failed to show amplification in a similar manner to acyclovir. Central nervous system (CNS) stimulantsCentral nervous system (CNS) stimulants: An extract of Swertia chirata significantly reversed the CNS-stimulating effects of the drug mangiferin in albino mice and rats (28). It was determined that two Swertia chirata constituents (swertiamarin and mangiferin) antagonize each other in vivo. Hepatotoxic agentsHepatotoxic agents: Several components of Swertia chirata are reported to be hepatoprotective in vitro (11; 29; 4; 30). These results are supported by histopathological examination of the liver of experimental rats (31). Urinary stone agentsUrinary stone agents: Extracts of sticks of Swertia chirata have been shown to inhibit the mineralization of urinary stone-forming minerals, such as calcium phosphate, oxalate, or carbonate (16).Swertia chirata/Herb/Supplement Interactions:

In animals, the amarogentin-rich extract caused a significant reduction in lipid peroxidation and inhibition of incidence by activating glutathione-S-transferase (GST), glutathione peroxidase (GPx), superoxide dismutase (SOD), and catalase (CAT) (34; 35; 36).
