valeric

adj. pertaining to the plant valerian; pertaining to valeric acid, of a sedative extracted from the valerian plant

Valeric acid, or pentanoic acid, is a straight-chain alkyl carboxylic acid with the chemical formula CH3(CH2)3COOH. Like other low-molecular-weight carboxylic acids, it has a very unpleasant odor similar to that of dirty socks. It is found naturally in the perennial flowering plant valerian (Valeriana officinalis), from which it gets its name. Its primary use is in the synthesis of its esters. Volatile esters of valeric acid tend to have pleasant odors and are used in perfumes and cosmetics.  Ethyl valerate and pentyl valerate are used as food additives because of their fruity flavors.
