Peach Kernel and Lotus Root Soup: Recipe & Medicinal Benefits

Introduction to Medicinal Diet

Peach Kernel and Lotus Root Soup with Lean Meat is a nourishing medicinal dish that combines therapeutic benefits with delicious flavor, originating from the folk soup-making wisdom of Lingnan region. Its main ingredients are peach kernel (Persicae Semen) to activate blood and resolve stasis, lotus root (Nelumbinis Rhizoma) to clear heat and cool blood, and lean meat to nourish yin and supplement blood, harmonized with fresh ginger (Zingiberis Rhizoma Recens). The soup has a clear broth and a sweet, savory taste. This therapeutic dish skillfully integrates medicinal herbs with food ingredients, preserving the rich flavor of the soup while regulating qi and blood as well as moistening the viscera and bowels. It is especially suitable for daily health maintenance during autumn and winter, or for individuals with blood stasis constitution.

Semen Persicae (Persicae Semen, peach kernel) is the dried ripe seed of *Prunus persica* (L.) Batsch or *Prunus davidiana* (Carr.) Franch. (Rosaceae). It is neutral in nature, bitter in taste, and enters the Heart (HT), Liver (LR), and Large Intestine (LI) meridians. Fresh lotus root (Nelumbinis Rhizoma, *Nelumbo nucifera* Gaertn.) clears heat and cools blood, while cooked lotus root fortifies the spleen and opens the stomach. Lean meat tonifies spleen qi and moistens the intestines and stomach. Simmering these three ingredients together creates a synergistic effect, rendering the soup mild in medicinal nature yet enduring in efficacy—a nourishing remedy suitable for all seasons.

Efficacy of Medicinal Diet

The main effects of this medicinal food are to activate blood and resolve stasis, moisten the intestines to promote bowel movements, and clear heat to moisten dryness. Tao Ren (Semen Persicae, peach kernel) is rich in fatty oils and amygdalin, which promote blood circulation and alleviate pain and irregular menstruation caused by blood stasis. Lian Ou (Nelumbinis Rhizoma, lotus root) contains abundant mucilage protein and dietary fiber; it can both clear heat and cool the blood to address bleeding and restlessness due to blood heat, and also promote intestinal peristalsis to relieve constipation.

Lean meat provides high-quality protein and iron, nourishing yin and supplementing blood (滋陰補血) while enhancing physical strength. When combined with Persicae Semen (peach kernel, 桃仁) and Nelumbinis Rhizoma (lotus root, 蓮藕), it synergistically alleviates symptoms such as sallow complexion, dry skin, and dry mouth and throat. Overall, this soup helps regulate a concurrent pattern of blood stasis with internal heat (血瘀內熱) and yin-blood deficiency (陰血不足), effectively addressing common modern issues like blood stasis from prolonged sitting, difficulty in defecation, and upward floating of deficient fire (虛火上浮).

The specific action of activating blood and resolving stasis

For blood stasis patterns such as dysmenorrhea in women, dark menstrual blood with clots, and persistent lochia after childbirth, a soup made with Persicae Semen (peach kernel) and Nelumbinis Rhizoma (lotus root) with lean meat can gently resolve stasis and promote the discharge of stagnant blood. At the same time, the blood-cooling and astringent properties of lotus root help prevent excessive bleeding. Long-term consumption may improve signs of blood stasis constitution, such as a dull complexion and purple lips and tongue.

The Role of Traditional Chinese Medicine

From the perspective of TCM property, flavor, and meridian tropism, peach kernel (Persicae Semen) is bitter and sweet in flavor, neutral in nature, and enters the Heart (HT), Liver (LR), and Large Intestine (LI) meridians. Bitterness facilitates descending and discharging, while sweetness nourishes and moistens; therefore, it activates blood and dispels stasis, and moistens the intestines to promote defecation. It is commonly used to treat traumatic injuries, blood stasis with swelling and pain, pulmonary abscess (lung abscess) and intestinal abscess, as well as constipation due to intestinal dryness. Lotus root (Nelumbinis Rhizoma) is sweet in flavor and cold in nature, entering the Heart (HT), Spleen (SP), and Stomach (ST) meridians. When used raw, it clears heat, generates fluids, cools the blood, and disperses stasis; when cooked, it tonifies the Spleen (SP) and benefits the Stomach (ST), stops diarrhea, and secures essence. Here, it is cooked into a soup to take advantage of its ability to strengthen the Spleen (SP) without causing stagnation, and to clear heat without damaging the righteous qi.

Lean pork is sweet and salty in flavor, neutral in nature, and enters the Spleen (SP), Stomach (ST), and Kidney (KI) meridians. It nourishes yin and moistens dryness, supplements qi and nourishes blood. In this combination, Persicae Semen (peach kernel) acts as sovereign to invigorate blood, Nelumbinis Rhizoma (lotus root) acts as minister to cool blood and strengthen the Spleen, lean meat acts as assistant to supplement deficiency, and Zingiberis Rhizoma Recens (fresh ginger) acts as envoy with its acrid-warm nature to prevent Persicae Semen and Nelumbinis Rhizoma from being excessively cold. Together, they achieve the effects of invigorating blood and cooling blood, strengthening the Spleen and moistening the Intestines, nourishing yin and moistening dryness. The entire formula addresses both the blood aspect and the qi aspect, enabling stagnant blood to be removed and new blood generated, heat pathogen to be cleared and yin fluids to be restored.

Indications

This medicated diet is especially suitable for individuals with Blood Stasis constitution, manifesting as a dull complexion, purple-dark lips, ecchymosis on the skin, engorged sublingual veins, dysmenorrhea or menstrual blood with clots in women, and fixed stabbing pain in specific body parts. It may also be consumed in appropriate amounts by those who experience poor lower limb blood circulation due to prolonged sitting and lack of exercise, as well as individuals in the recovery stage of traumatic injuries or with sequelae of stroke accompanied by Blood Stasis pattern.

Additionally, for those with yin deficiency and dryness-heat or internal disturbance of blood-heat—such as dry mouth and throat, dry stools, irritability and insomnia, or dry, scaly skin—consuming this soup can clear heat, moisten dryness, relieve constipation, and calm the spirit. It is also suitable for elderly individuals with habitual constipation due to yin and blood deficiency and loss of intestinal moisture, as well as for breastfeeding women with persistent postpartum lochia accompanied by constipation.

Contraindicated populations

Pregnant women are strictly contraindicated. Persicae Semen (peach kernel) has a relatively strong effect of activating blood and resolving stasis. Modern pharmacological studies show that the amygdalin it contains can be decomposed in the body to produce hydrocyanic acid, which is mildly toxic. Consumption by pregnant women can easily induce uterine contractions, increasing the risk of miscarriage. In addition, the dosage of Persicae Semen should not be excessive; the recommended daily dosage for adults is 3–10 grams. This formula has already been strictly controlled.

Contraindicated in patients with bleeding disorders (such as thrombocytopenic purpura, hemophilia, or active gastrointestinal bleeding) to avoid exacerbating hemorrhage. Caution is also advised in those with Spleen-Stomach Deficiency Cold pattern (manifested as epigastric cold pain, poor appetite with loose stools, aversion to cold, and cold extremities), as lotus root is cooling in nature and peach kernel moistens the intestines; their combined use may easily damage Spleen Yang and potentially lead to diarrhea. Those with loose stools or diarrhea, as well as individuals with hypotension, should avoid excessive consumption.

Ratio of Ingredients in the Formula

Persicae Semen (Peach Kernel): 10 g (approximately one small handful) Nelumbinis Rhizoma (Lotus Root): 200 g (fresh, peeled and cut into pieces) Pork lean meat: 150 g (cut into pieces, blanched to remove blood foam) Zingiberis Rhizoma Recens (Fresh Ginger): 3 slices (approximately 10 g, crushed) Purified water: 1500 ml Salt: appropriate amount (for final seasoning)

The above is for 2–3 servings. Lotus root should be chosen from mature (old) lotus root, which has a soft, glutinous texture and offers better heat-clearing effects. For the lean pork, pork loin or leg meat is preferred due to its low fat content, resulting in a clear, sweet soup. As for peach kernel (桃仁), should one select bitter apricot seed (bitter almond) or sweet apricot seed (sweet almond)? Here it specifically refers to bitter apricot seed (Semen Armeniacae Amarum, i.e., medicinal peach kernel), which must be soaked in warm water in advance to remove the skin and tips in order to reduce its toxicity. If this processing is inconvenient, stir-fried peach kernel (stir-fried bitter apricot seed) can be used directly.

Preparation Method

Step 1: Prepare the ingredients. Soak Persicae Semen (peach kernel) in warm water for 30 minutes in advance, then peel off the skin and remove the pointed tip (bitterness and toxicity are mainly concentrated in the tip). Drain and set aside. Peel the lotus root and cut into rolled chunks about 2 cm thick, then rinse with clean water to remove starch. Cut lean pork into 2 cm cubes. Place the pork in cold water in a pot, add 1 slice of Zingiberis Rhizoma Recens (fresh ginger), bring to a boil over high heat, skim off the foam, then remove the pork and rinse with warm water.

Step 2: Place the prepared peach seeds (Persicae Semen), lotus root (Nelumbinis Rhizoma), lean pork, and the remaining 2 slices of fresh ginger (Zingiberis Rhizoma Recens) into a clay pot or ceramic casserole. Add enough clean water (about 1500 ml). Bring to a boil over high heat, then reduce to low heat, cover, and simmer for 1.5–2 hours. Stir once or twice during this period to prevent the lotus root from sticking to the bottom. Turn off the heat when the lotus root becomes soft and sticky, the lean pork is tender, and the soup turns slightly yellow.

Step 3: Use a fine-mesh strainer or ladle to skim off surface oil. Season with table salt according to personal taste (a small amount is recommended to enhance freshness; avoid over-salting). Optionally, garnish with a sprinkle of chopped scallions or goji berries (not essential). Ladle into bowls and serve warm. The peach kernels (Semen Persicae) and lotus root (Rhizoma Nelumbinis) are both edible; the lean meat can be picked up and dipped in soy sauce as a side dish.

Drinking Tips

1. This decoction should be consumed warm in the afternoon or before dinner, 200–300 ml per serving, 2–3 times per week. It may be taken continuously for no more than two weeks; if long-term regulation is needed, resume after a one-week interval.

2. Persicae Semen (Peach Kernel) is slightly toxic; it must be used after peeling and removing the tips, and the dosage should not exceed 10 grams. It is not recommended for pregnant women, nursing mothers, or children. If the decoction develops a distinct bitter almond flavor (abnormal bitterness), discontinue use immediately.

3. Lotus root (Nelumbo nucifera) oxidizes and turns black easily after cutting; it is recommended to cut it just before use. If preparation in advance is needed, soak the cut lotus root in diluted vinegar water to prevent discoloration. When making soup, avoid using iron pots, as they may cause the lotus root to turn black and affect both color and texture.

For those with a Spleen and Stomach deficiency pattern, add 2 dried jujubes (Ziziphus jujuba, red dates, pitted) while boiling to moderate the cold nature. If dry stool or severe constipation occurs, add a small amount of honey (Mel, stir in after turning off heat, temperature not exceeding 50°C). Those with a deficiency-cold constitution should combine with ginger slices (Zingiber officinale) to warm the Middle Burner, or substitute with stir-fried peach kernels (Semen Persicae, Prunus persica).
