Pear, Sugarcane & Imperata Root Drink (Zhu Zhe Mao Gen Xue Li Shui)
Pear, Sugarcane & Imperata Root Drink is a classic Lingnan folk dietary remedy for clearing summer heat, quenching thirst, and generating fluids. It has been described as "not a herbal tea, yet better than a herbal tea; not a sweet soup, yet better than a sweet soup" . Mr. She Ziqiang, a pharmacist at Guangdong Provincial Hospital of Traditional Chinese Medicine, specifically recommended this formula. Pear moistens the lungs and clears heart fire; bamboo cane moistens and generates fluids, benefits the stomach, and quenches thirst; Bai Mao Gen cools blood, stops bleeding, clears heat, and promotes diuresis, with a mild and gentle nature that is "cooling yet not cold" . Together, pear moistens the lungs and resolves phlegm, sugarcane clears heat and generates fluids, and Imperata root cools blood and promotes diuresis. The drink achieves the effects of clearing summer heat, quenching thirst, generating fluids, moistening the lungs, clearing heart fire, reducing internal heat, soothing the throat, and promoting diuresis . The liquid is clear with a pale yellow tint, sweet and refreshing, carrying the distinctive fragrance of sugarcane and Imperata root. It is especially suitable for summer heat with internal fire, dry throat from staying up late, autumn dryness cough, and scanty dark urine.

Main Ingredients
- Pear 2 pieces
- Fresh sugarcane (or bamboo cane) 400-500g
- Fresh Imperata cylindrica root (Bai Mao Gen) 100g
- Water chestnuts 6-8 pieces
- Carrot 1 piece
- Rock sugar to taste
- Water 1500-2000ml
Steps
Prep Imperata root: Rinse 100g of fresh Bai Mao Gen (or 30-50g dried) thoroughly, remove impurities, and cut into small sections. If using dried, soak in water for 30 minutes first. Prep sugarcane: Peel 400-500g of sugarcane, cut into 3cm sections, then split each section into 4 pieces to release active compounds . Prep pear: Wash 2 pears, keep the skin on (scrub with fine salt), remove the core, and cut into small pieces. If using water chestnuts or carrot, peel and cut into pieces.

Place Imperata root sections and sugarcane sections in a clay pot. Add 1500-2000ml of water (about 6-8 bowls). Bring to a boil over high heat, then reduce to low heat and simmer for about 20 minutes .

Add the pear pieces and simmer for another 10 minutes . If using water chestnuts or carrot, add them with the pear.

The liquid is naturally sweet, so no sugar is generally needed. Add a little rock sugar if desired. Turn off the heat, strain out the solids, and collect the liquid. Drink warm, or at room temperature. 1-2 times per week is sufficient; avoid daily excessive consumption .
