What is it

AI-assisted evidence assessment — talk to your doctor before relying on any single supplement.

Anxiety / sleep (traditional)

Mixed Evidence

Traditional Chinese medicine and folk use for restlessness and insomnia. No published high-quality controlled human trials.

Weight management (leaf extract)

Mixed Evidence

Small studies of lotus leaf extract suggest modest effects on lipid profile and weight; results are inconsistent.

How it works

Different lotus parts contain different active compounds. Lotus seeds and embryo contain alkaloids (neferine, liensinine) with sedative, anti-arrhythmic, and antihypertensive activity in preclinical studies. Lotus leaves contain nuciferine and flavonoids associated with anti-obesity and lipid-lowering effects in animals. The rhizome is a starchy food. Blue lotus (Nymphaea caerulea) contains apomorphine and nuciferine and has been historically used as a mild psychoactive 'dream' herb, although human controlled data are minimal. Mechanisms vary by species and plant part; most claimed benefits rely on traditional use or laboratory work rather than rigorous clinical trials.

Dosage

No standardized dose. Traditional preparations range from 3-12 g of dried plant material as a tea or decoction. Modern extracts vary widely in standardization.

When and how to take it

Lotus seed and rhizome are usually consumed as food. Calming lotus preparations (such as seed embryo or blue lotus tea) are typically taken in the evening. Lotus leaf extracts for metabolic support are often taken with meals.
