title: Capsaicin in hot chili pepper: carcinogen, co-carcinogen or anticarcinogen?
abstract: Capsaicin (trans-8-methyl-N-vanillyl-6-nonenamide) is a major pungent ingredient of the Capsicum fruits such as hot green and red peppers. Besides its use as a food additive in various spicy cuisines, capsaicin is currently utilized for therapeutic purposes to treat various peripheral painful conditions such as rheumatoid arthritis and diabetic neuropathy. Considering consumption of capsaicin as a food additive and its current medicinal application in humans, correct evaluation and precise assessment of any harmful effects of this compound are essential from the public health standpoint. Numerous investigations have been conducted to determine the potential mutagenic and carcinogenic activity of capsaicin and chili pepper, but results are discordant. This review briefly examines findings in the literature of studies testing mutagenicity and tumorigenicity of capsaicin and presents a possible mechanistic basis for the dual effects exerted by the compound.
