The evidence in words

What it is

Hops (Humulus lupulus) is used for sleep and anxiety, and contains phytoestrogens.

How it works

It has mild sedative and GABAergic activity; the 8-prenylnaringenin content is a potent phytoestrogen.

What the evidence shows

Modest sleep-quality evidence, mostly in combination with valerian; standalone data are limited. Its strong phytoestrogen warrants caution in hormone-sensitive contexts.

Safety & interactions

Generally safe; phytoestrogenic — caution in hormone-sensitive conditions. Valerian — The classic sleep-blend pairing.

Bottom line

A mild sleep herb best known in valerian-hops blends. Modest; mind the phytoestrogen if relevant.
