Ilex Pubescens and Pig Trotters: Benefits, Recipe, and Cautions

Introduction to Medicinal Diet

Ilex pubescens (毛冬青) and Pig Trotters Stew is a classic medicinal diet that embodies the wisdom of Lingnan tradition and Traditional Chinese Medicine (TCM) health preservation. It is especially popular in damp-heat regions such as Guangdong and Guangxi. Ilex pubescens is the dried root of the plant Ilex pubescens Hook. et Arn. (family Aquifoliaceae). Its nature and flavor are bitter, astringent, and neutral, and it enters the Heart (HT), Lung (LU), and Liver (LR) meridians. Since ancient times, it has been a commonly used folk herb for regulating the blood vessels, clearing heat, and detoxifying. Pig trotters are rich in collagen and various amino acids. They can both nourish yin and moisten dryness, and also supplement qi and enrich the blood. When stewed together, the broth is rich in color and full-bodied in flavor. The medicinal ingredients leverage the nourishing power of the food, and the food supports the action of the medicine, creating an excellent product that “uses the meal as nourishment.”

The name of this medicinal diet itself embodies the fusion of natural ingredients and herbal essence: the root of Ilex pubescens (毛冬青) is used for its ability to unblock the meridians and remove toxins, while pig trotters (猪脚) are simmered in the soup for their nourishing and moistening effect. In the Lingnan region, this soup is commonly prepared during autumn and winter, or when one experiences sluggish blood circulation and a heavy sensation in the joints. It can be served as a daily meal accompaniment or as an adjunct dietary therapy for post-illness recuperation, and its gentle yet lasting regulating effect has earned widespread trust among the people.

Efficacy of Medicinal Diet

The core benefits of Ilex pubescens (Mao Dongqing) stewed with pig’s trotters center on three aspects: “activating blood and unblocking meridians, clearing heat and resolving toxin, and nourishing joints.” The active components in Ilex pubescens, such as ilex saponins and flavonoids, can dilate coronary arteries and increase blood flow while inhibiting platelet aggregation, positively improving blood circulation and preventing thrombosis. The collagen in pig’s trotters, after slow simmering, transforms into gelatin, which helps lubricate joints and repair cartilage tissue, offering adjunctive relief for joint stiffness and pain.

From a nutritional perspective, this medicinal dish also helps strengthen immunity and promote skin health. The heat-clearing action of Ilex pubescens (pubescent holly root) assists in eliminating internal heat toxin, thereby improving skin issues caused by blood heat. The elastin and collagen abundant in pig trotters help maintain skin elasticity and delay aging. Therefore, regular moderate consumption of this soup not only regulates the health of the blood vessels and mai (vessels) but also leaves the complexion rosy and radiant, achieving a holistic health effect that nurtures both interior and exterior.

Additionally, stewed pig trotters with Ilex pubescens (Mao Dong Qing) can also support vascular health in individuals with the “three highs” (hypertension, hyperlipidemia, and hyperglycemia). Studies show that active compounds in Ilex pubescens help reduce blood viscosity, aid in regulating blood lipids and blood pressure, while the collagen in pig trotters enhances the resilience of blood vessel walls. The synergistic effects of these ingredients make this medicinal dish a preferred dietary therapy for cardiovascular health.

The Role of Traditional Chinese Medicine

Invigorate blood and unblock collaterals, clear heat and resolve toxin.

In TCM theory, Ilex pubescens (Mao Dong Qing) is bitter in flavor and neutral in nature, specifically enters the blood vessels. It has the clear actions of “activating blood and unblocking the meridians, clearing heat and detoxifying.” Bitterness can drain, dry, and harden; therefore, Ilex pubescens can drain heat-toxin from the blood aspect and unblock stasis and stagnation within the vessels. It has a good regulating effect on conditions such as joint redness and swelling, limited flexion and extension, and heart vessel obstruction (cardiac vessel blockage) due to blood-heat with blood stasis. Pig trotters, on the other hand, are sweet in flavor and neutral in nature, enter the Kidney (KI) and Stomach (ST) channels. They can “supplement deficiency and consumption, replenish Kidney essence, and strengthen the lower back and knees.” The combination of the two, one clearing and one supplementing, allows the stasis and stagnation to be unblocked and the deficiency and consumption to be replenished, achieving the delicate balance of “unblocking without damaging the upright (rectifying qi), and supplementing without retaining pathogens.”

Nourish the Liver and Kidney, strengthen sinews and bones.

In Traditional Chinese Medicine, the kidney governs the bones and the liver governs the sinews; therefore, the health of bones and sinews is closely related to the充足ness of liver and kidney essence. Pig trotters enter the Kidney Meridian (KI), nourishing kidney yin and moistening the bone marrow. Combined with the blood-vessel-unblocking action of *Ilex pubescens* (pubescent holly), this effectively relieves symptoms such as soreness and weakness of the lower back and knees, difficulty in walking, and cold pain in the joints due to Liver and Kidney deficiency with blood stasis obstructing the vessels. For the common degenerative joint diseases in middle-aged and elderly populations, the warm-moistening nature of this medicinal diet not only alleviates pain but also nourishes the liver and kidney from the root. Regular consumption over time helps delay joint degeneration and improve quality of life.

Indications

This medicinal dish of *Ilex pubescens* (Pubescent Holly root) stewed with pig trotters is particularly suitable for individuals with symptoms related to “impeded blood circulation,” such as office workers and elderly individuals who often experience cold extremities, numbness in the limbs, heaviness in the lower legs, or varicose veins. For those whose blood circulation has declined due to prolonged sitting and lack of exercise, regular consumption of this medicinal food can help improve peripheral circulation and alleviate coldness, soreness, and distension in the limbs. Additionally, patients with mild cardiovascular and cerebrovascular issues (such as stable coronary heart disease or insufficient blood supply to the brain) may benefit from moderate intake under medical guidance as an adjunct to regulate Qi and blood circulation.

This medicinal diet is also highly suitable for individuals with joint discomfort, including middle-aged and elderly patients with degenerative arthritis, women experiencing postpartum joint pain, and young people with joint strain from exercise. The rich collagen and calcium content in pig’s trotters, combined with the collateral-dredging effect of Ilex pubescens (pubescent holly), can effectively reduce joint inflammation and lubricate joint spaces. It offers notable relief for soreness, weakness, and pain in the knees and ankles. Additionally, those with rough skin, dull complexion, or those seeking to improve skin texture can use this medicinal diet as a daily beauty dietary therapy formula.

Contraindicated populations

Individuals with Spleen and Stomach Deficiency Cold accompanied by loose stools should use with caution or avoid consuming Ilex pubescens (Maodongqing) stewed with pig’s trotters. Ilex pubescens is neutral in nature but tends toward clearing and draining, while pig’s trotters are cloying and greasy in texture. For those with weakened Spleen and Stomach transportation and transformation functions, this combination may aggravate symptoms such as abdominal distension, diarrhea, or indigestion. If such individuals still wish to use it, they should first regulate the Spleen and Stomach, or add small amounts of Citri Reticulatae Pericarpium (Chenpi) and Zingiber officinale (Shengjiang) to the medicinal diet to regulate Qi and harmonize the Stomach, and the quantity consumed each time should not be excessive.

Pregnant women and those during menstruation should avoid consumption. Ilex pubescens (hairy holly) has the effect of activating blood and unblocking collaterals (vessels). Ingestion during pregnancy may stimulate uterine contractions, increasing the risk of miscarriage or preterm labor; consumption during menstruation may lead to increased menstrual flow and prolonged period duration. Additionally, individuals with hypotension should use caution, as the vasodilating effect of Ilex pubescens may further lower blood pressure, causing symptoms such as dizziness and fatigue. Those allergic to Ilex pubescens or pig trotters should avoid consumption.

Proportions of Ingredients in a Formula

Dried Ilex pubescens root: 30 g (fresh Ilex pubescens root may use 50 g, must be washed and sliced). Ilex pubescens root is the core medicinal herb of this medicated diet. It is recommended to select high-quality dry goods with greyish-brown bark, firm texture, and yellowish-white cross-section for better therapeutic effect.

Fresh pig trotters: 500g (approximately half a trotter; ideally the front trotters, as they have thicker flesh and richer collagen content). After cutting into pieces, soak in clean water for 30 minutes to remove some of the blood. Then blanch before cooking to ensure a clear broth and pure flavor.

Ingredient ratio: 6 red dates (Fructus Jujubae, pitted), 4 slices fresh ginger (Rhizoma Zingiberis Recens), 15 ml yellow rice wine, appropriate amount of salt. The red dates neutralize the bitter and astringent taste of Radix Ilicis Pubescentis (Ilex pubescens root) while enhancing its blood-nourishing effect; fresh ginger and yellow rice wine serve to remove fishy odors, enhance aroma, warm the Middle Burner, and dispel Cold. Additionally, 3 grams of dried tangerine peel (Pericarpium Citri Reticulatae) can be prepared and added for patients with weak Spleen and Stomach, as it helps regulate Qi and harmonize the Stomach.

Preparation Method

Step 1: Quickly rinse the dried Ilex pubescens root (Mao Dong Qing) under clean water to remove surface dust. Place it in a basin, add cold water, and soak for 30 minutes to allow full hydration and softening, facilitating the release of active constituents. After soaking, cut the root diagonally into thin slices approximately 3 cm in length and set aside.

Step 2: Cut the pig trotters into chunks, then place them in cold water with 2 slices of ginger (Zingiber officinale) and 10 ml of yellow rice wine (huangjiu). Bring to a boil over high heat and continue to blanch for 5 minutes, skimming off the foam. Remove the pig trotters and immediately rinse them in warm water to clean off any remaining impurities and fishy odor. Drain well and set aside.

Step 3: Place the prepared *Ilex pubescens* (Mao Dong Qing) slices, pork trotter chunks, Chinese dates (*Ziziphus jujuba*), the remaining ginger slices, and tangerine peel (*Citri Reticulatae Pericarpium*) together into a clay pot (or ceramic casserole). Add enough clean water to submerge the ingredients by about 5 cm. Bring to a boil over high heat, then reduce to low heat, cover, and simmer for 2.5 to 3 hours, until the pork trotters are tender and the soup turns a light reddish-brown color.

Step 4: Ten minutes before turning off the heat, add 5 ml of yellow wine (rice wine) and an appropriate amount of salt, stir evenly, and continue simmering on low heat to allow the flavors to fully blend. After turning off the heat, do not immediately remove the lid; let it sit for about 15 minutes to allow the soup to become richer. Before serving, remove the residue of Ilex pubescens (hairy holly root) — as the fibers are coarse and inedible — leaving only the trotters and soup for consumption.

Drinking Tips

1. It is recommended to consume 1 to 2 times per week, one bowl (approximately 300 ml) each time. After three consecutive weeks of consumption, take a one-week pause to allow the body an interval for absorption and regulation. Avoid excessive or frequent consumption, as this may over-nourish and burden the spleen and stomach.

2. The best time for consumption is between 9-11 AM (when the Spleen Meridian (SP) is in charge) or 3-5 PM (when the Bladder Meridian (BL) is in charge), as during these periods the body’s absorptive capacity is stronger and the utilization rate of medicinal effects is higher. Taking it on an empty stomach or one hour after meals yields better results. Avoid taking it immediately after meals to prevent interference with digestion.

3. If the prepared medicinal soup is not consumed in one sitting, it can be stored in the refrigerator, but not for more than 24 hours. When reheating, bring it to a full rolling boil. For optimal texture, store the pig trotters separately from the broth; otherwise, prolonged soaking will cause the trotters to lose elasticity, compromising both taste and nutritional quality.

4. During the course of administration, if symptoms of internal heat (excessive heat) such as dry mouth, sore throat, or constipation appear, appropriately reduce the dosage of Ilex pubescens (Pubescent Holly root) to 20 g, or add 10 g of Ophiopogon japonicus (Dwarf Lilyturf tuber) to the decoction to nourish yin and clear heat. If loose stools or stomach cold (stomach cold pattern) occur, increase the amount of Zingiber officinale (Ginger) to 6 slices and add 3 grains of Piper nigrum (White pepper) to warm the middle burner and warm the stomach.
