Sour Jujube Seed
酸枣仁 · Suān Zǎo Rén
Quiets restless sleep and anxious palpitations
What it does
Sour jujube seed quiets the sleep where you wake at 3 a.m. with a racing mind, plus the anxious palpitations and night sweats. In TCM, it nourishes the liver and calms the spirit, the pattern behind insomnia from internal restlessness. Jujuboside compounds show sedative effects in animal studies. Distinct from regular jujube, the warming red date.
How to take it
Decoct 9–18g of dried sour jujube seeds (lightly crushed) in 4 cups water for 30 minutes. Drink 1 cup 30 minutes before bed. Pair with longan or lily bulb.
Try a sour jujube seed tea 30 minutes before bed when sleep is restless
Take a standardized sour jujube seed capsule (typically 500mg) 30 minutes before bed. Often combined with reishi, longan, or lily bulb in sleep formulas.

Where it comes from
Sour jujube seed (Ziziphus jujuba var. spinosa) comes from the wild thorny variety of the same plant that gives us sweet red dates. The seed is the medicinal part. It's the lead herb in Suān Zǎo Rén Tāng, a 1,800-year-old classical formula recorded in the Jin Gui Yao Lue for insomnia and night sweats from liver-blood depletion. Modern Chinese sleep aids often build on this formula, combining sour jujube with lily bulb and biota seed.
