Pig Tail Soup with Flemingia & Cibotium: Expel Wind-Dampness

Introduction to Medicinal Diet

“Pig’s Tail Stewed with Flemingia and Cibotium” is a traditional medicated dietary recipe originating from the Lingnan region, whose core actions are to expel wind and eliminate dampness, and to strengthen sinews and bones. In the formula, *Flemingia philippinensis* (Philippine flemingia), also known as “Qianjin Diao” (thousand-jin hanger), has roots resembling iron bones and is folk-used for treating lower back and leg pain. *Cibotium barometz* (golden chicken fern) refers to the rhizome of the golden chicken fern, named for its dense golden hairs on the surface, and it specifically enters the Liver and Kidney meridians. Pig’s tail, with more bones than marrow, is rich in collagen and calcium, complementing the herbal effects. This soup is milky white in color and has a rich, mellow flavor. It serves both as a dish and a remedy, especially suitable for those in the Lingnan region suffering from summer dampness and heat with a feeling of heaviness and weakness in the lower back and knees.

The formulation of medicinal cuisine follows the principle that “medicinals borrow the power of food, while food assists the authority of medicinals.” Flemingia philippinensis root (Qianjinba) and Cibotium barometz rhizome (Gouji) are both essential herbs for dispelling wind-damp and strengthening sinews and bones, while pig tail tonifies the kidney and enriches the marrow, allowing the medicinal effects to directly target the lumbar spine. During the slow-cooking process, the active components are fully extracted and combine with proteins and amino acids, resulting in a warm, moist texture without the bitterness of medicinal dregs. Traditionally, people in the Lingnan region often prepare this soup during the plum rain season or the transition between autumn and winter to prevent chronic cold-damp leg pain and recurrence of wind-damp disorders.

Efficacy of Medicinal Diet

Overall, the soup of Flemingia philippinensis (Philippine flemingia) and Cibotium barometz (golden moss) stewed with pig tail has the effects of tonifying the liver and kidney, strengthening the lower back and knees, dispelling wind-dampness, and benefiting the joints. It serves as a good auxiliary regulation for chronic lumbar muscle strain, lower back pain and soreness caused by lumbar disc herniation, as well as osteoporosis in middle-aged and elderly people, and degenerative changes of the knee joints. Additionally, the gelatin in the soup lubricates the joints and improves the stiffness that hinders smooth movement.

From a modern nutritional perspective, pig tail is rich in collagen, calcium, and phosphorus, which help maintain bone resilience. Flemingia philippinensis (Philippine flemingia) contains flavonoids and saponins with anti-inflammatory and analgesic activities. Cibotium barometz (golden chicken tail fern) contains pterosins and other constituents that promote joint synovial fluid secretion. The synergistic effect of these three components can delay cartilage degeneration and reduce aseptic inflammation in the joints, making them particularly suitable for Wind-Damp Bi Pain with Liver and Kidney Deficiency.

Functions of Traditional Chinese Medicine

Tonify the Liver and benefit the Kidney, strengthen sinews and bones

According to Traditional Chinese Medicine, the Liver governs the sinews and the Kidney governs the bones; the strength of the sinews and bones relies entirely on the nourishment of Liver and Kidney essence and blood. Flemingia root (Flemingia philippinensis), with a neutral nature and sweet, astringent taste, enters the Liver and Kidney meridians; it excels in dispelling wind-dampness and strengthening the lower back and knees, and is especially suitable for soreness and weakness of the lower back and knees due to Liver and Kidney deficiency. Cibotium (Cibotium barometz), with a bitter-sweet taste and warm nature, specifically enters the Liver and Kidney meridians; it can tonify the Liver and Kidney, strengthen the lower back and knees, and dispel wind-dampness; its hairs, when applied externally, can also stop bleeding and promote tissue regeneration. Pig tail, following the principle of “like treats like,” guides the medicinal effects into the lower back and spine. The combination of these three substances ensures that Kidney qi is abundant and Liver blood is sufficient, thereby naturally strengthening the sinews and bones.

Dispel Wind-Dampness, unblock collaterals, and stop pain.

When wind-dampness evil lodges in the channels and collaterals, qi and blood become stagnant and astringent, leading to joint swelling and pain. *Flemingia philippinensis* (Qianjinba) can “benefit the joints and dispel dampness,” while *Rhizoma Cibotii* (Gouji) is adept at “penetrating the joints and dispersing cold-dampness.” Used together, they can dredge and unblock obstruction in the Foot-Taiyang Bladder Channel and the Governor Vessel. When decocted into a soup, the medicinal power becomes gentle and harmonious. For chronic rheumatoid arthritis and lumbago-leg pain aggravated by overcast and rainy days, this combination effectively relieves spasm and the sensation of heaviness, without impairing the Spleen and Stomach.

Suitable Population

1. Lumbar muscle strain and lumbar disc herniation: For lower back soreness and distension, as well as morning stiffness caused by prolonged sitting or heavy lifting, the soup may be taken 2–3 times per week for one consecutive month to consolidate the therapeutic effect. 2. Osteoporosis or osteophytosis in middle-aged and elderly individuals: Presenting with knee weakness and pain when ascending or descending stairs, this soup can supplement calcium and promote its absorption, thereby alleviating irritation caused by bone spurs. 3. Postpartum or postoperative lower back and spinal pain: In women after childbirth, qi and blood deficiency combined with kidney qi impairment often leads to a sensation of ice-coldness in the lower back; during the postoperative recovery period, this soup can also facilitate the healing of tendons and bones.

Additionally, individuals who live year-round in damp environments and are prone to joint pain due to wind-cold invasion, as well as young adults with high physical activity who develop knee joint effusion and fasciitis from overtraining, may also modify the herbs of this formula accordingly. It should be noted that during the period of taking the formula, consumption of raw and cold fruits should be avoided to prevent impairment of the stomach.

Contraindicated Populations

1. Contraindicated in cases with pronounced Damp-Heat pattern: Manifested as red, swollen, hot, and painful joints, thirst with dark urine, and a yellow, greasy tongue coating – this is Damp-Heat Bi obstruction. Mistaken supplementation would fuel fire, aggravating swelling and pain. 2. Early stage of acute injury (within 48 hours): Local bleeding and edema have not yet subsided; ice application and immobilization are required. Premature warming supplementation should be avoided, as it may exacerbate exudation. 3. External contraction with unresolved fever: The decoction is warm and supplementing in nature, which may easily induce “trapping the pathogen inside,” making it difficult to expel the pathogenic factor. 4. Use with caution in Spleen-Stomach Yang Deficiency with loose stools: Pig tail is rich in gelatinous substance, and the medicinal ingredients are slightly warming. If accompanied by diarrhea, remove the pig tail fat or add 3g of Chenpi (Citri Reticulatae Pericarpium) when decocting to regulate Qi and harmonize the Stomach.

Pregnant women should avoid taking large doses, as Cibotii Rhizoma (dog spine) has the potential to promote blood circulation (ancient herbal texts state it “unblocks the blood vessels”); however, small amounts of pig tail are safe for consumption. Individuals allergic to the herbal material (e.g., those who develop a rash upon contact with the fuzz of dog spine) should also avoid its use. Additionally, patients with severe hypertension or acute gout episodes (hyperuricemia) should refrain from consumption, as pig tail contains a moderate level of purines, which may lead to fluctuations in uric acid levels.

Proportions of Food Ingredient Formula

Main ingredient: 1 fresh pig tail (about 300–400 grams), cut into sections and set aside.

Ingredients: Flemingia philippinensis root (dry) 30g (fresh 60g may be used), Cibotium barometz rhizome (dry) 20g (hairs must be scraped off first to avoid throat irritation).

Adjuncts: 2 honeyed jujubes (approx. 15g, to harmonize the medicinal flavors), 3–5 slices fresh ginger (approx. 10g), 10ml aged yellow rice wine (to remove fishy odor and enhance fragrance), appropriate amount of table salt (approx. 3–5g, for seasoning before serving).

Water amount: After all ingredients are in the pot, add 1.5–2 liters of clean water (about 8 bowls of water). After simmering, the soup yields approximately 4–5 bowls, enough for 2–3 servings.

Note: It is recommended to wrap Flemingia philippinensis (Qianjin Ba) and Cibotium barometz (Golden Hair Dog Spine) in a muslin bag for easy removal during consumption. If fresh pig tail is unavailable, 300 g of pig spine bones can be used as a substitute, though the gelatin content will be slightly inferior. Do not add too many honey dates to avoid an overly sweet taste that masks the herbal aroma.

Cooking Method

Step 1: Prepare the main ingredient. Singe any residual hair roots from the pig tail over an open flame, then scrape and wash it clean. Cut into 3–4 cm segments. Place in cold water in a pot, add 2 slices of ginger (Zingiber officinale) and 5 ml of yellow rice wine (Huangjiu). Bring to a boil over high heat, skim off any foam, then boil for another 2 minutes. Remove the pig tail and rinse thoroughly with warm water to remove surface grease and blood stains.

Step 2: Processing the herbs. Quickly rinse Flemingia root (Flemingia philippinensis) with clean water, then soak in warm water for 20 minutes to soften it; gently brush Cibotium rhizome (Cibotium barometz) with a soft brush to remove surface fuzz, wash clean, then place both into a gauze bag together, and tie the bag tightly.

Step 3: Simmer the soup. Place the pork tail segments, herb sachet, honey dates, and the remaining ginger slices into a ceramic clay pot or electric slow cooker. Add sufficient pure water. Bring to a boil over high heat, then reduce to low heat and simmer slowly for 1.5–2 hours. If using an electric slow cooker, select the “Soup” mode for 2 hours.

Step Four: Season and finish. Simmer until the pig tail is tender and the soup turns milky white. Use chopsticks to remove the herb bag (discard). Add the remaining yellow rice wine and salt, then continue cooking for another 5 minutes before turning off the heat. When serving, sprinkle a few goji berries (Lycium barbarum) or chopped scallions as desired.

Tips for Consumption

1. The optimal time for administration is between 5–7 PM (during the Kidney meridian time, KI) or one hour before bedtime, as absorption efficiency is higher during these periods, and the calcium content in the decoction helps calm the spirit and promote sleep. Avoid taking it immediately after meals to prevent diluting gastric juices and impairing digestion.

2. Recommended course: Take 2–3 times per week for 3 consecutive weeks as one treatment cycle. For long-term consolidation, take 7–10 days per month. After acute pain subsides, switch to once weekly for maintenance.

3. Dietary Contraindications: During the medication period, avoid ice cream, cold drinks, and cold-natured fruits and vegetables (e.g., watermelon, bitter melon) to prevent damaging Spleen Yang and reducing medicinal efficacy. If concurrently taking other Chinese medicinals (e.g., Aconiti Lateralis Radix Praeparata [Fuzi], Aconiti Radix [Wutou]), allow an interval of at least 2 hours.

4. Reuse of herbal residue: The pig tail after simmering can be eaten dipped in soy sauce, but the herbal residue (especially the hairs of Cibotium barometz) should not be consumed. After removing the herb bag, it can be decocted once more to obtain the liquid for foot soaking, which provides auxiliary relief for heel pain.
