How to read this herb page
This page is structured to help readers move from naming and traditional context into kitchen use, comparison links, and caution notes without scrolling blindly.
What this herb is
Lotus Leaf (He Ye) is primarily used to clear Summer-Heat and resolve Dampness — making it the classic herb for the heavy, sluggish, and overheated feeling of a hot, humid summer. It is also used to raise the clear Yang Qi of the Spleen. In the kitchen, it is most famously used to wrap sticky rice (Lo Mai Gai) before steaming, imparting its distinctive clean, earthy fragrance. This page explores its traditional context, active compounds, and versatile uses.
We show the English name, pinyin, Chinese characters, and Latin name together so readers can connect grocery familiarity, traditional terminology, and reference naming in one place.
How traditional writing groups it
In traditional language, nature describes whether a herb is warming, cooling, neutral, and so on. Flavor refers to a traditional framework such as sweet, bitter, pungent, sour, or salty, each with its own functional associations.
- Nature: Neutral to slightly cool
- Flavor: Bitter, mild
- Traditionally associated with: Liver, Spleen, Stomach
Channel entry is a traditional term. It describes traditional functional relationships, not a direct claim about modern anatomy.
Traditional context in plain English
- In traditional Chinese wellness practices, Lotus Leaf (He Ye) is bitter and neutral. It primarily enters the Liver, Spleen, and Stomach channels.
- Clearing Summer-Heat and resolving Dampness — the classic herb for the heavy, sluggish, overheated feeling of a hot, humid summer day.
- Raising the clear Yang Qi of the Spleen — helps lift energy and clear the head, addressing that foggy, heavy-headed feeling associated with Dampness.
- Cooling the Blood — traditionally used when Heat affects the blood level, particularly in the context of Summer-Heat patterns.

Best way to start with this page
- Lotus leaf works best when readers meet it through visual tea language and pantry habits rather than through aggressive search expectations.
- A short seasonal tea page usually explains this leaf more naturally than theory-heavy copy alone.
What the science says
To provide a well-rounded view, it is helpful to look at how authoritative health organizations evaluate lotus leaf. Lotus Leaf is considered an adaptogen—a natural substance theorized to stimulate the body's resistance to physical, environmental, and emotional stress [1].
Active Compounds
Lotus leaf is exceptionally rich in nuciferine — a unique aporphine alkaloid — as well as quercetin, kaempferol, and various other flavonoids and polyphenols. Nuciferine is the primary focus of modern metabolic research on lotus leaf.
Metabolic and Lipid Support
Nuciferine has been studied for its potential to inhibit the absorption of dietary fat and carbohydrates in the digestive tract, and to support healthy lipid metabolism. Multiple studies have investigated lotus leaf extract in the context of healthy weight management and metabolic wellness, with promising results in preclinical and some clinical studies.
Cardiovascular Support
The flavonoids in lotus leaf, particularly quercetin, have well-documented antioxidant and anti-inflammatory properties that support cardiovascular wellness. This provides a scientific basis for its traditional use in the context of summer wellness and Dampness-related health patterns.
How to read this page in context
A herb profile is an educational overview, not a full practice guide. In traditional practice, herbs are often combined, prepared in different ways, and interpreted according to pattern, constitution, season, and dose.
That is why HerbGuide emphasizes careful wording, cultural context, food use examples, and safety notes instead of presenting any one herb as a universal answer.
A better next step is to pair this profile with Evening Teas and Warming vs Cooling Foods .
Safety note and interactions
This page is an educational reference built around traditional herb writing and publicly available research summaries. It is not a wellness recommendation, a substitute for professional guidance, or a claim that this herb is appropriate for any specific person.
