1. Origin and description

Lotus Plumule is the dried young embryo located in the center of mature lotus seeds, from the lotus plant, belonging to the lotus family (Nelumbonaceae).

The dried herb is usually small, slender, slightly curved, and green to yellowish green. It breaks easily when dry, has a light odor, and tastes very Bitter. Good quality material should be evenly dried, naturally green, free from moisture, mold, and unusual odor.

Because this herb absorbs moisture easily, it should be stored in a sealed container in a dry place. When used as herbal tea, only a small amount is needed. A tea that is too strong may taste extremely bitter and may feel too Cold for people with weak digestion.

2. Related names of Lotus Plumule

Other names: Tâm sen, Tim sen, Liên tử tâm, Mầm hạt sen.

Scientific herbal name: Embryo Nelumbinis nuciferae. Pinyin name: Lian Zi Xin. Chinese name: 莲子心.

It is important to distinguish this herb from the white lotus seed. Lotus seed is commonly used as food and as a nourishing herb, while the green embryo in the center is much more Bitter and mainly used to clear Heart heat and calm the mind.

3. Flavors, Nature – Meridian

In TCM, Lotus Plumule has a Bitter flavor and a Cold Nature. The Bitter flavor helps drain fire and reduce irritability, while the Cold Nature helps clear heat. This makes the herb more suitable for patterns with internal heat, restlessness, dry mouth, thirst, or sleep difficulty related to heat.

The herb commonly enters the Heart and Kidney Meridians. The Heart is connected with the spirit, sleep, and palpitations. The Kidney is connected with essence, yin, and internal balance. Therefore, this herb is often used when Heart fire is strong, when Heart and Kidney are not communicating well, or when sleep is disturbed by heat and agitation.

4. Benefits of Lotus Plumule in TCM

Lotus Plumule is best known for clearing the Heart and calming the spirit. In simple words, it helps cool down the feeling of being overheated, irritated, restless, or unable to relax. When insomnia is linked with Heart irritability or internal heat, this herb may help the body settle more easily before sleep.

Common traditional benefits include clearing Heart fire, removing irritability, calming the mind, supporting better sleep, easing mild palpitations, reducing thirst caused by heat, and supporting cases of seminal emission or dream emission when the pattern matches. Some traditional use also mentions high blood pressure with palpitations and poor sleep, but it should not replace prescribed medication.

5. How to use and dosage

Lotus Plumule is often used as herbal tea, decoction, or part of a multi-herb formula. A common reference dosage is 1.5–3 g per day. Some references use 2–4 g/day depending on body constitution, purpose, and combination.

• Herbal tea: Use a small amount, rinse quickly, then steep with hot water and drink warm during the day.
• Decoction: Boil with other herbs when a stronger formula effect is needed.
• Powder: Use only with clear dosage because the taste is very Bitter.
• Combination: Often used with Suan Zao Ren, Bai Zi Ren, Yuan Zhi, roasted Tâm sen, Mai Men Dong, or Gan Cao.

Do not make the tea too concentrated or drink it continuously for a long period without understanding the cause of insomnia.
