Mint Leaf (Bo He): A Cooling Herb for the Lungs, Throat, and Digestive Health
Introduction
Mint Leaf, known as Bo He (薄荷) in Traditional Chinese Medicine (TCM), is the dried aerial part of Mentha haplocalyx or Mentha arvensis. Celebrated for its refreshing aroma and cooling nature, Mint disperses wind-heat, clears the head and eyes, soothes the throat, and supports healthy digestion. In both TCM and Western herbalism, it is valued for its ability to relieve headaches, ease indigestion, and calm the mind, offering a natural sense of clarity and rejuvenation.
What Is Mint Leaf
Bo He is an aromatic, cool, and slightly pungent herb that primarily enters the Lung and Liver meridians. It helps release exterior heat, disperse stagnation, and restore balance when the body experiences symptoms of heat or tension. In the West, mint is equally cherished for promoting digestion, freshening breath, and relieving minor discomforts. Whether steeped as a tea or added to herbal soups, mint provides a crisp, invigorating flavor and gentle medicinal benefits.
Health Benefits of Mint Leaf
Clears Wind-Heat and Soothes the Throat
In TCM, Bo He is used to expel wind-heat, relieve sore throat, and ease headaches or red eyes caused by common colds or seasonal heat.
Promotes Digestion and Relieves Bloating
Mint relaxes the digestive tract, alleviating nausea, gas, and indigestion. It stimulates bile flow and supports smooth digestion after heavy meals.
Refreshes the Mind and Relieves Stress
The aroma of mint clears the head, sharpens focus, and helps calm emotional irritability, making it a natural aid for mental fatigue.
Eases Nasal and Respiratory Discomfort
Mint’s cooling and aromatic oils help open nasal passages, soothe coughs, and relieve mild respiratory congestion.
Supports Skin and Detoxification
Bo He promotes gentle sweating and detoxification, helping clear minor rashes or heat-related skin irritations.
How to Use Mint Leaf
In Herbal Preparations
Bo He is typically added near the end of decoction (for about 5–10 minutes) to preserve its essential oils. It combines well with herbs such as Ju Hua (Chrysanthemum), Sang Ye (Mulberry Leaf), or Lian Qiao (Forsythia Fruit) to relieve wind-heat and soothe the throat.
In Daily Teas or Soups
Fresh or dried mint leaves can be steeped as tea or added to light soups. Try pairing mint with honey, lemon, or goji berries for a cooling, fragrant drink that supports digestion and relieves heat.
In TCM Formulas
Mint is a key ingredient in formulas such as Yin Qiao San (Honeysuckle and Forsythia Powder) for early-stage colds and sore throats, and Sang Ju Yin (Mulberry Leaf and Chrysanthemum Decoction) for coughs and eye irritation due to wind-heat.
Where to Buy Mint Leaf
You can find Bo He at Chinese herbal shops or TCM pharmacies, health food stores, and tea retailers, or from online herbal suppliers such as iHerb, Amazon, or ChineseHerbsDirect.
Look for bright green or light brown dried leaves with a crisp aroma, clean and dry leaves without moisture or mold, and organic or lab-tested products for purity and safety.
Are There Any Side Effects
Mint Leaf is generally safe and well-tolerated. However, excessive use may cause mild stomach upset or chills in people with cold constitutions. Avoid using it during pregnancy or in cases of yin deficiency with heat signs without professional guidance.
Conclusion
Mint Leaf (Bo He) is a refreshing and versatile herb that clears heat, supports digestion, and soothes the throat and mind. Whether used in teas, soups, or TCM formulas, it harmonizes the body’s systems, promoting clarity, comfort, and gentle rejuvenation—a true herbal classic across both Eastern and Western traditions.
