What it does
Lotus seed steadies chronic loose stools, calms restless sleep with palpitations, and supports vaginal health. In TCM, it strengthens the spleen and kidneys, the systems that hold things in place. It also nourishes the heart and quiets the spirit, helping with anxiety-driven insomnia. Common in the Si Shen porridge mix with coix and Chinese yam.
How to take it
Soak 9–15g dried lotus seeds for 2 hours, then simmer in soup or congee for 1 hour. Common pairing with red dates and Chinese yam for digestive support.

Where it comes from
Lotus seeds come from the same lotus plant whose leaves and flowers also have TCM uses. Each seed has a hard outer shell that's removed before consumption. The white embryo inside (Lián Zǐ Xīn) is bitter and used separately for restless heart-fire. Lotus seeds are common in Chinese desserts like sweet soups and mooncakes, and they're considered both food and medicine. One clinical trial explores their effects on lipid markers.
