Linn.
Family: Anacardiaceae.
Habitat: Native to tropical America, from Mexico to Peru and Brazil. Cultivated largely in Malabar, Kerala, Karnataka, Tamil Nadu and Andhra Pradesh, and to some extent in Maharashtra, Goa, Orissa and West Bengal.
English: Cashew Nut.
Unani: Kaaju.
Siddha/Tamil: Mindiri.
Action: Leaves and bark—fungi- cidal, vermicidal, protozoicidal, antimicrobial (used for toothache, sore gums). Karnel—eaten for its high protein content. Cashew apple—antiscorbutic. Resinous juice contained in the seeds—used in cases of mental derangement, memory disturbances, palpitation of heart, rheumatic pericarditis, sexual debility.
The nut contains 45% fat and 20% protein. Leaves contain flavonoids, mainly glycosides of quercetin and kaempferol, and hydroxybenzoic acid. The bark contains a balsam-containing anacardic acid, anacardol, cardol and ginkgol. The caustic liquid in the shell contains about 39% anacardic acid, a mixture of alkyl salicylic acid derivatives. The leaves are febrifuge. Anacardic acid is bactericidal, fungici- dal, vermicidal and protozoicidal. The leaves and bark exhibited hypotensive activity in rats.The phenolics of the cashew-nut shell oil have inhibited the enzymic activity of alpha-glucosidase, invertase and aldose reductase (anacardic acids being the most potent). Cardols have also shown antifilarial activity in vitro. Anacardic acids, cardols and methyl cardols have been found to exhibit moderate cytotoxic activity.

Family: Anacardiaceae.
Habitat: Punjab, Assam, Khasi Hills, Madhya Pradesh and Peninsular India.
English: Marking-Nut.
Ayurvedic: Bhallaataka, Bhallata, Arushkara, Agnik, Agnimukha, Sophkrit, Viravrksha.
Unani: Balaadur, Bhilaayan, Bhilaavaan.
Siddha/Tamil: Shenkottei, Erimugi. (Kattu shen-kottai is equated with S. travancorica Bedd., found in evergreen forests of Tinnevelly and Travancore.)
Folk: Bhilaavaa.
Action: Toxic drug, used only after curing. Fruit—caustic, astringent, anti-inflammatory, antitumour. Used in rheumatoid arthritis and for the treatment of tumours and malignant growths.
A decoction, mixed with milk or butter fat, is prescribed in asthma, neuralgia, sciatica, gout, hemiplegia, epilepsy. Kernel oil—antiseptic; used externally in gout, leucoderma, psoriasis and leprosy. Bark gum—used for nervous debility; in leprous, scrofulous and venereal affections.Bigger var. is equated with S. kurzii Engler.The nut shells contain biflavonoids, including tetrahydrobustaflavone, tet- rahydroamentoflavone and anacardu- flavanone; nallaflavone; anacardic acid; aromatic amines and bhilawanol. Bhi- lawanol is a mixture of phenolic compounds, including cis and trans isomers of urushenol (3-pentadecenyl-8' catechol), monohydroxy phenol and semicarpol. These are the major constituents of the shell liquid, isolated from the nuts (about 46% of the weight of extract).A mixture of closely related pentade- cyl catechols exhibits anticancer activity. Extracts of the fruit was found effective against human epidermoid carcinoma of the naso-pharynx in tissue culture.Milk extract of the nut showed anti-inflammatory activity against car- rageenin, 5-HT and formaldehyde- induced rat paw oedema in acute anti- inflammatory studies. (About 20% animals developed gangrene of limbs, tail and ears.)
Dosage: Detoxified fruit—1-2 g in milk confection. (API, Vol. II.)... semecarpus anacardium
