What is Lv E Mei?

Lv E Mei is the dried flower bud of the Chinese plum tree (Prunus mume). It is also known as green plum flower or Japanese apricot flower. It is a single drug, which means one herb on its own, not a blend.

In Chinese medicine it is used as a light, aromatic tea. It is given for a tight chest, a full feeling after meals, and poor appetite. It is also used for low mood tied to stress, and for a lump-in-the-throat feeling with no clear cause.

Here is the plain verdict. The herb has a long record of use in one tradition. Human trials are missing, so we cannot say it works.

Long use is not proof of effect, and we will not repeat that point in each section below.

How does Lv E Mei work?

No one has shown how this herb acts in the body. Any account of how it works is a best guess.

Chinese medicine describes it as moving "stuck liver qi". In plain words, that means it is used when stress seems to bind up the chest and stomach. Practitioners call it a gentle herb that soothes without drying the body out.

Lab work on the plum tree points to plant acids and scent oils that can relax smooth muscle in a dish. That is test-tube work, not proof of an effect in people.

What forms does Lv E Mei come in?

Whole dried flower buds are the usual form. You steep a pinch in hot water like a tea.

You may also see it in these forms: - In a mixed herbal formula written by a practitioner - In a granule or powder that dissolves in hot water - Blended into scented tea products with green tea or jasmine

Tinctures and capsules of this single flower are uncommon.

Where it comes from:

The plum tree has been grown in China for thousands of years for its fruit and its winter flowers. The flower bud entered the herbal record later than the fruit.

It is named in Qing dynasty texts, notably Zhao Xuemin's supplement to the Compendium of Materia Medica (1765). It stayed a modest, food-like herb rather than a heavy hitter.

It is used mainly in China, and to a lesser degree in Japan and Korea.

What does Lv E Mei help with?

• Tight or full feeling in the chest during stress: This is the classic use. Chinese texts list it for a chest that feels bound up when a person is under strain. No human trial has tested it for this.
• Poor appetite with fullness after meals: It is used as a light tea before or after food to settle the stomach. The idea is that the scent moves food along. Evidence in people is absent.
• A lump-in-the-throat feeling with no clear cause: Chinese medicine calls this "plum-pit qi". The herb is a common part of formulas for it. Any throat lump that lasts, hurts, or makes swallowing hard needs a doctor first, not a tea.
• Low mood and irritability linked to stress: Traditional texts frame it as a calming, mood-easing herb. There are no trials in people with depression or anxiety. Do not use it in place of treatment for a mood disorder.
• Mild cough with sticky phlegm: A minor traditional use, often in a blend rather than alone. The warm steam and fluid may be doing much of the comfort work. No trial evidence supports it.

Which foods are rich in Lv E Mei?

1. Scented Chinese green tea: the dried flowers are sometimes blended in for aroma
2. Plum flower congee (rice porridge): a home dish in parts of China
3. Steamed buns and sweet soups: the flowers are used now and then as a garnish

Practical Tips:

Food amounts are small and are used for scent, not for any health claim.

What are the side effects of Lv E Mei?

• Mild stomach upset or nausea, mostly on an empty stomach
• Loose stools when a lot is taken
• Dry mouth or throat
• Allergic reaction in people sensitive to plum, apricot, cherry or almond
• Skin rash or itching, rarely

Good to know:

Side effects are uncommon and mild. This is a food-like flower used as a weak tea, and no serious harm has been reported from normal use.

The main real risk is allergy. The plum tree is in the rose family, along with apricot, cherry, peach and almond. If those bother you, this may too.

How much Lv E Mei should you take?

• Recommended daily: There is no dose proven by research. What follows is common practice, not a tested amount. Chinese materia medica lists 3 to 6 grams of the dried flower buds per day. That is roughly a teaspoon or two of the light, dry buds. As a tea, steep the buds in just-boiled water for about 5 minutes. Most people drink one to three cups a day. If a practitioner gave you a formula, follow their amount instead.
• Best time of day: Most people drink it in the afternoon or early evening, when stress and stomach fullness tend to peak. There is no evidence that timing matters.
• With or without food: Either works. For fullness after eating, people usually drink it 20 to 30 minutes after a meal. If tea on an empty stomach makes you queasy, take it with food.
• Time to effect: Any calming or settling feeling from a warm tea comes within minutes. There is no proven longer-term effect to wait for.
• How long to take it: Short runs are the norm. Try it for two to four weeks, then stop and see if anything changed. If nothing has changed after four weeks, it is unlikely to help you. If your symptoms are worse at any point, stop and get advice.
