Linn.
Family: Grossulariaceae.
Habitat: Cold temperate regions extending from Himalayas to northern Asia and Europe.
English: European Black Currant.
Folk: Nabar.
Action: Dried leaves and twigs— a home remedy for coughs. Leaves—diuretic, hypotensive, refrigerant. An infusion is used for inflammatory conditions, sore throat, hoarseness. Fruits— refrigerant, mildly spasmolytic, vasoprotective, anti-inflammatory.
Black currents are very rich in vitamin C (average 150 mg/100g) and contain 0.9-1.7% pectin as calcium pec- tate, also minerals, potassium (372 mg/ 100 g). The acidity of the fruit is mainly due to citric acid; malic acid is present in small amounts. Glucose and fructose are principal sugars; sucrose is a minor component.The flavonoids in the fruits include kaempferol, quercetin and myricetin. About 0.3% anthocyanosides, concentrated mainly in the skin, consist of glycosides of cyanidol and delphinidol.The anthocyanosides are reportedly bacteriostatic and exhibit vasopro- tective and anti-inflammatory activity. They are antisecretory against cholera toxin-induced intestinal fluid secretion in vitro.The leaves contain an anti-inflammatory principle, pycnometol and minute quantities of an essential oil composed mostly of terpenes.Polyphenolic extract of buds inhibited lipid peroxidation by rat liver mi- crosomes.Polyphenols present in R. nigrum and R. rubrum (Red Current, Western Himalayas from Kumaon to Kashmir) exhibit free radical scavenging activity. The seed oil lowers VLDL and total cholesterol.Contraindicated in bleeding disorders. (Sharon M. Herr.)

Family: Myrsinaceae.
Habitat: Throughout India.
English: Embelia.
Ayurvedic: Vidanga, Krmighna, Krmihara, Krmiripu, Chitratandula, Jantughna, Jantunaashana, Vella, Amogha.

Action: Ascaricidal, anthelmintic, carminative, diuretic, astringent, anti-inflammatory, antibacterial, febrifuge. Used in diseases of chest and skin. Active principles are found to be oestrogenic and weakly progestogenic. Root—bechic, antidiarrhoeal. Seed—spermicidal, oxytocic, diuretic. The plant is also used for its blood purifying properties. It is an ingredient in cough syrups, preparations for anaemia, genitourinary tract infections, diarrhoea and diseases of the liver.
Embelin, isolated from the berries, shows significant anti-implantation and post-coital antifertility activity. (Successful trials have been carried out at the National Institute of Immunology, New Delhi on human beings.) It is found to be a potential male antifer- tility agent. Spermatogenesis has been impaired and sperm count reduced to the level of infertility. The antisper- matogenic changes are found to be reversible without any toxic effects.Aqueous and EtOH extract of the fruit—anthelmintic against earthworms. Fruit powder (200 mg/kg), taken with curd on empty stomach, expelled tapeworm within 6-24 h. The treatment was also found effective in giardiasis. EtOH (50%) of the plant was found slightly active against E.coli. Di-salts of embelin—an- thelmintic. Amino salts exhibited less side effects than embelin. The effect of di-isobutyl amino derivatives lasted up to 10 h, also showed anti-inflammatory, hypotensive and antipyretic activities.Berries gave quinones—embelin, ra- panone, homoembelin, homorapnone and vilangin.
Dosage: Fruit—5-10 g powder. (API Vol. I.)... embelia ribes
