Acute Toxicity Study of “Gadagi” Tea on Rats

Abstract

Acute toxicity study was carried out on three most common types of “Gadagi” tea preparations, “sak’’,”sada” and “magani”.. LD₅₀ values of each type of the tea were determined. Results of phase I and phase II of the study showed no mortality was recorded in any of the experimental groups of rats in 24hours and up to four weeks after oral administration of 5000mg/kg of each type of the tea. Hence, oral administration of all the “Gadagi” tea preparations studied at a dose of less than or equal to 5000mg/kg (equivalent to 7.90cm³, 6.90cm³ and 8.20cm³ for “sak”, “sada” and “magani” respectively) could be safe.
