Sangjisheng Stewed Eggs: Chinese Mistletoe Medicinal Food Guide

Sangjisheng (Taxillus chinensis, Mulberry Mistletoe) Stewed Eggs: A Medicinal Food Guide

Introduction to Medicated Diet

Mulberry Mistletoe Stewed Eggs is a widely circulated traditional Lingnan medicinal diet. The core ingredient, mulberry mistletoe, consists of the dried leafy stems and branches of either *Taxillus chinensis* (Chinese taxillus) or *Viscum coloratum* (colored mistletoe) from the family Loranthaceae. This medicinal dish is prepared by simmering mulberry mistletoe together with eggs, yielding a light brown broth with a delicate herbal aroma and a warm, smooth taste. It is a classic folk recipe for regulating the Liver and Kidneys, nourishing Blood, and calming the Fetus. The use of mulberry mistletoe has a long history. As early as the *Shennong Bencao Jing* (Divine Farmer’s Classic of Materia Medica), it was listed as a superior-grade herb, stating that it “treats lower back pain, stiffness of the back in children, abscesses and swellings, calms the Fetus, plumps the skin, strengthens the hair and teeth, and promotes the growth of the beard and eyebrows.”

The preparation of this medicinal dish is extremely simple. Wash the Chinese taxillus (Sang Ji Sheng, *Taxillus chinensis*) and place it in a pot with eggs. Add an appropriate amount of water and simmer slowly. Once the eggs are fully cooked, crack the shells and allow them to steep for a while longer so the medicinal liquid fully penetrates the egg whites. The final product allows one to both eat the eggs and drink the soup, blending medicine and food in a gentle tonic that is nourishing without being harsh. It is especially suitable for individuals with weak constitutions who require long-term regulation and can be taken as a daily side dish. Due to its neutral nature, it is commonly used in home kitchens in Guangdong and Guangxi as a restorative after childbirth or menstruation.

Efficacy of Medicinal Diet

The overall benefits of Taxillus chinensis (Chinese taxillus) stewed with eggs focus on four aspects: tonifying the Liver and Kidney, strengthening the sinews and bones, nourishing blood and calming the fetus, and expelling wind-dampness. From a nutritional perspective, eggs provide high-quality protein, lecithin, and various trace elements, while Taxillus chinensis is rich in flavonoids, quercetin, and trace elements such as zinc and manganese. The combination synergistically enhances the body’s reparative capacity. With regular moderate consumption, it can improve symptoms such as soreness and weakness of the lower back and knees, and dizziness and blurred vision due to Liver and Kidney deficiency. At the same time, it has a good preventive and auxiliary regulatory effect on fetal restlessness (threatened miscarriage) and habitual abortion.

Additionally, this medicinal food also has a certain ameliorative effect on sallow complexion and dry skin caused by blood deficiency pattern. The property of Taxillus chinensis (Chinese mistletoe) to dispel wind and unblock collaterals can alleviate wind-damp impediment pain, making it especially suitable for middle-aged and elderly individuals to use for joint care in autumn and winter. The entire formula is neither cold nor hot in nature, tonifying without being cloying; it can serve both as a medicinal treatment and a dietary nourishment, embodying the profound wisdom of “medicine and food share a common origin” in Traditional Chinese Medicine. Modern research further suggests that the active constituents in Taxillus chinensis have a positive effect on dilating coronary arteries and increasing coronary blood flow, thereby offering auxiliary health benefits for patients with mild hypertension or coronary heart disease as well.

The Role of Traditional Chinese Medicine

From the perspective of Chinese medicinal properties, flavors, and meridian tropism, Sangjisheng (Taxillus chinensis, Chinese taxillus) is bitter and sweet in flavor, neutral in nature, and enters the Liver (LR) and Kidney (KI) meridians. Bitterness can dry dampness, sweetness can tonify and supplement, while its neutral nature renders its medicinal effects gentle and enduring. In the formula, Sangjisheng primarily serves to tonify the liver and kidneys, strengthen sinews and bones, dispel wind-dampness, and secure the fetal root. The liver governs sinews and the kidneys govern bones; when the liver and kidneys are ample, sinews and bones are robust and the fetal root is stable. At the same time, its action of dispelling wind and eliminating dampness can clear pathogenic factors from the channels and collaterals, relieving impediment pain (bi syndrome). The egg (dan), sweet in flavor and neutral in nature, enters the Lung (LU), Spleen (SP), and Stomach (ST) meridians, and can nourish yin, moisten dryness, enrich blood, and calm the spirit. As a guiding and harmonizing agent (zuoshi) in the formula, it both supplements nutrition and moderates the medicinal properties while enhancing palatability.

The combination of these two ingredients creates a formula pattern that “tonifies the middle and simultaneously unblocks”: *Taxillus chinensis* (Chinese taxillus) tonifies the Liver and Kidney while also dispelling Wind-Damp, and *Gallus domesticus* egg (egg) nourishes blood and yin while also moistening dryness. One tonifies, one unblocks; one ascends, one descends, so that the whole formula both fills the deficiency of the Lower Origin and unblocks stagnation in the channels and collaterals. Especially for pregnant women, when Liver blood is sufficient, the fetus is nourished; when Kidney qi is secure and firm, the fetus is anchored. This formula achieves the purpose of calming the fetus by regulating and tonifying the Liver and Kidney, which precisely conforms to the TCM principle of “treating the root of the disease.” For postpartum blood deficiency with joint soreness and pain, this formula also produces the effects of nourishing blood to dispel Wind and relieving Bi (painful obstruction) to stop pain.

Suitable Population

It is most suitable for individuals with soreness and pain in the lower back and knees, as well as weakness of the sinews and bones, due to Liver and Kidney Deficiency. Such individuals often experience aggravated lower back pain after fatigue, weak and sore knees, difficulty climbing stairs, and may also be accompanied by symptoms such as dizziness, tinnitus, and frequent nocturia. Stewed eggs with *Taxillus chinensis* (Chinese mistletoe) can nourish the Liver and Kidney, strengthen the sinews and bones, and long-term consumption may gradually improve the above symptoms. Additionally, for patients with Wind-Damp Bi pattern, especially those with chronic rheumatic arthritis or senile degenerative osteoarthropathy presenting with cold pain in the joints and impaired flexion and extension, consuming this dish can assist in dispelling Wind and Cold, unblocking collaterals, and relieving pain.

Pregnant women experiencing threatened abortion or habitual abortion may use this as a supplementary dietary therapy under a physician’s guidance. For those with pale complexion, dry and lusterless hair, and dry skin caused by blood deficiency failing to nourish, as well as for postpartum women with insufficient lactation and lower back pain, this formula can also nourish blood, moisten dryness, unblock collaterals, and promote lactation. Middle-aged individuals suffering from lumbar muscle strain and fatigue due to prolonged sitting and staying up late in a modern work environment may also adopt this diet as a simple daily nourishing option. However, it should be noted that any medicinal diet must be based on accurate pattern differentiation and should not be followed blindly.

Contraindicated Populations

It is not suitable for consumption during exterior excess patterns such as common cold with fever, cough and copious phlegm. Although Taxillus chinensis (Chinese parasitic herb) has tonifying effects, its neutral nature is slightly obstructive; taking it during external contractions may cause pathogens to linger and prolong the disease course. In any acute infection manifestations such as fever, sore throat, nasal congestion, or yellow nasal discharge, the medicated diet should be paused first, and regulation should resume only after recovery. It is also inappropriate for those with exuberant internal damp-heat, presenting symptoms such as bitter taste, yellow greasy tongue coating, sticky loose stools, and dark yellow urine, because the tonifying nature of Taxillus chinensis may promote dampness and generate heat, aggravating damp-heat obstruction.

Those with a known allergy to eggs or Sangjisheng (Taxillus chinensis, Chinese taxillus) must absolutely avoid this preparation. Additionally, individuals with Spleen and Stomach Deficiency Cold pattern, often presenting with frequent loose stools or diarrhea, should use it with caution, as egg protein is relatively difficult to digest and the small amount of fiber in Sangjisheng may irritate the intestinal tract. Pregnant women must consult a professional Chinese medicine practitioner before consumption, to determine suitability and appropriate dosage based on individual constitution and gestational stage. For children, the dosage should be reduced to one-third or one-quarter of the adult dose, and prolonged continuous use is not recommended. In any individual, if adverse reactions such as skin rash or gastric discomfort occur during use, the preparation should be discontinued immediately and medical attention sought.

Proportions of food ingredients in the formula

The standard formula for Taxillus Herba (Sangjisheng) Stewed Eggs is as follows: 15–20 grams of dried Taxillus Herba (Sangjisheng), 1–2 fresh eggs, and 600–800 ml of water. Depending on individual constitution and needs, 3–5 Fructus Jujubae (Hongzao, pitted), 2–3 slices of fresh Zingiberis Rhizoma Recens (Shengjiang), or a small amount of brown sugar may be added to enhance flavor and efficacy. For miscarriage prevention, add 10 grams of Dipsaci Radix (Xuduan) and 12 grams of Cuscutae Semen (Tusizi). For strengthening sinews and bones, add 10 grams of Achyranthis Bidentatae Radix (Niuxi) and 12 grams of Eucommiae Cortex (Duzhong). For pronounced blood deficiency, add 15 grams of Lycii Fructus (Gouqi) and 10 grams of Longan Arillus (Guiyuanrou).

It should be specifically noted that the dosage of *Taxillus chinensis* (Chinese taxillus) should be controlled between 15 and 20 grams; excessive amounts may cause gastrointestinal discomfort. The number of eggs is generally recommended at 1–2 per day, as too many may increase the digestive burden. The water level should be approximately 2 cm above the ingredients, and the final decoction should yield about 300–400 ml. If the herbs contain sand or impurities, they should be rinsed quickly before preparation, but prolonged soaking should be avoided to prevent loss of active constituents. This formula is for a single adult dose, taken once daily. It is advisable not to exceed two consecutive weeks of use, after which a few days’ interval should be observed before resuming.

Preparation Method

Step One: Material Preparation

Weigh 15–20 g of dried *Taxillus chinensis* (mulberry mistletoe). Rinse quickly under running water or sift through a fine mesh sieve to remove dust, then soak in clean water for about 10 minutes until slightly softened. Wash the shells of 1–2 eggs; if possible, choose free-range or native chicken eggs for better nutritional value. Prepare an earthenware or ceramic pot, avoiding iron or aluminum pots to prevent alteration of medicinal properties.

Step 2: Decoction

Pour the soaked *Taxillus chinensis* (Chinese mulberry mistletoe) together with the soaking water into a pot, then add enough plain water to bring the total volume to 600–800 mL. Place the washed eggs into the pot, cover with a lid, and bring to a boil over high heat. Immediately reduce to a low heat and simmer for about 20 minutes. At this point, the eggs will be cooked. Gently crack the eggshells with a spoon to create fissures, but do not peel them off. Continue simmering over low heat for another 10–15 minutes to allow the herbal liquid to fully permeate the eggs.

Step Three: Flavor Adjustment and Liquid Reduction

Before turning off the heat, add an appropriate amount of brown sugar (Saccharum sinensis) or rock sugar to taste, stirring until dissolved. For individuals with a Cold Constitution, add 2–3 slices of fresh ginger (Zingiber officinale) when cracking the egg and cook together. To enhance the blood-tonifying effect, add pitted red dates (Ziziphus jujuba) 5 minutes before removing from heat. After cooking, remove the egg, peel off the shell, and strain the decoction through a fine sieve to remove the herbal residue. Return the egg to the soup for immediate consumption, or soak the egg (with shell) in the soup until cooled, then refrigerate. Reheat the next day before eating.

Drinking Tips

1. Best Time for Administration: It is recommended to take it warm on an empty stomach before breakfast or lunch, when the Spleen and Stomach have stronger transportation and transformation ability, allowing full absorption of the medicinal effect. Evening consumption may affect sleep due to slower protein digestion, so it is not advisable at dinner.

2. Administration cycle and observation: Take continuously for 7–10 days as one cycle, then discontinue for 3–5 days before continuing. During administration, carefully observe body reactions. If symptoms such as dry mouth, constipation, or dark yellow urine appear, reduce the dosage of Taxillus chinensis (Sangjisheng) to 10 g or temporarily suspend for a few days.

3. Contraindications and Precautions: During the course of taking this medicinal diet, it is advisable to avoid consuming strong tea, coffee, and spicy or irritating foods concurrently, as these may interfere with the absorption of the medicinal effects. If the patient is currently taking other Chinese herbal formulas or Western medications, it is recommended to allow an interval of at least one hour before consuming this medicinal diet, in order to prevent potential herb-drug interactions.

4. Storage and Reheating: If a large volume is decocted at one time, the medicinal liquid and the egg may be separated and refrigerated, but not for more than 24 hours. When consuming again, be sure to reheat thoroughly until boiling; do not consume cold. The longer the egg is soaked, the deeper the infusion, but if soaked for more than 8 hours, it should be discarded to prevent spoilage.
