"Abrus precatorius", called "Gulaganji" in Kannada, "kundu mani" in Tamil, "Guruvinda ginja" in Telugu and 'Kunni kuru' in Malayalam, has been used in Siddha medicine for centuries. The white variety is used to prepare oil that is claimed to be an aphrodisiac. A tea is made from the leaves and used for fevers, coughs and colds. Seeds are poisonous and therefore are only consumed after heat treatment. The Tamil Siddhars knew about the toxic effects in plants and suggested various methods which is called "suththi seythal" or purification. This is done by boiling the seeds in milk and then drying them. Like with castor oil, the protein toxin is denatured when subjected to high temperatures rendering it innocuous.
