Valerianic acid is sedative. The resin components, lupulon and humulon are antiseptic against Grampositive bacteria. Asparagin is diuretic. Research suggested that the anti- spasmodic effect is stronger than the sedative, and hops also possess antihis- taminic and anti-oxytocic properties. (Cases of amenorrhoea and dysmen- orrhoea are treated with hops.)Hop extracts exert different effects on CNS in mice. They show hypother- mic, hypnotic, sedative, muscle relaxing and spontaneous locomotor activities, besides potentiating pentobarbital anaesthesia in mice.Humulone inhibited induced inflammation in mice.The dried strobila containing humu- lone and lupulone showed antidiabetic activity in experimental rats.Hop mash or extract is used in the preparation of toothpaste for inhibiting Gram-positive bacteria and in hair preparations for preventing dandruff formation. It is also used in skin- lightening creams.
