Traditional Gypsum, Tofu, and Dried Cabbage Soup Recipe to Support Overall Wellness

Introduction to Medicinal Diet

Gypsum, Tofu, and Dried Cabbage Soup is a traditional heat-clearing medicinal diet originating from the Lingnan region. Its main ingredients include raw Gypsum Fibrosum (sheng shi gao), tofu, and dried Chinese cabbage, harmonized with small amounts of fresh ginger (sheng jiang) and honeyed jujube dates (mi zao) during slow simmering. The soup boasts a clear, bright appearance and a mild, elegant flavor. It is suitable both as a daily table accompaniment and as a home support during the transition between spring and summer or when dryness and internal heat (shang huo) arise.

In this formula, Gypsum Fibrosum (gypsum) is a mineral medicinal, tofu is a common bean product, and dried Chinese cabbage is obtained through sun-drying. The combination of these three ingredients is ingenious, preserving the freshness of the food while incorporating the clearing and moistening effects of the medicinals. This medicinal diet has been passed down among the people for a long time, especially in southern China, where many families stew this soup when they feel internal heat, in order to help soothe discomfort such as dry mouth and tongue, sore throat, and irritability. It is simple to prepare and the ingredients are easy to obtain, making it a vivid practice of the concept of the homology of medicine and food.

Historical Origins and Folk Application

Although records of the Gypsum, Tofu, and Dried Cabbage Soup are not found in ancient classical medical texts, it is deeply rooted in folk dietary culture. In the Lingnan region, where the climate is hot and damp, people have long explored many dietary therapy formulas aimed at supporting the body’s natural cooling and dampness balance, and this soup is a representative example. In the old days, farmers would often sun-dry surplus cabbage for storage, and when needed, cook it together with tofu and gypsum to both supplement nutrition and help maintain comfort.

Efficacy of Medicinal Diet

Gypsum, Tofu, and Dried Chinese Cabbage Soup has the core effects of supporting the body’s natural cooling and moistening processes. Gypsum excels at helping to maintain balance in the body’s heat phase. Tofu can help promote qi and support stomach harmony, while supporting the body’s natural cooling functions. Dried Chinese cabbage helps support lung comfort, intestinal health, stomach nourishment, and fluid balance. Their combined effect helps the body maintain internal harmony and replenish fluids.

Specifically, this decoction may help support comfort during temporary warm sensations, lung-related cough and breathing discomfort, stomach-related tooth sensitivity, and throat swelling. Additionally, as the decoction is rich in water and electrolytes, consumption can help maintain the body’s fluid levels, support metabolism, and assist in restoring a state of balance. When consumed regularly during dry seasons or in hot environments, it also helps support the body’s natural defenses against discomfort such as oral sensitivity and occasional bowel irregularity.

Modern nutrition perspective

From a modern nutritional perspective, gypsum is rich in mineral elements such as calcium and sulfur, tofu provides high-quality plant protein and isoflavones, and dried cabbage retains dietary fiber and various vitamins. This soup not only supports internal comfort but also provides nutritional support, making it particularly suitable for individuals with mild electrolyte imbalances caused by fever or excessive sweating.

The Role of Traditional Chinese Medicine

According to Traditional Chinese Medicine theory, Gypsum (Shi Gao) is acrid, sweet, and greatly cold in nature, entering the Lung (LU) and Stomach (ST) meridians. It is an essential herb for supporting the body’s natural cooling and purging functions, particularly adept at helping to maintain balance in the Lung and Stomach. In the formula, Gypsum serves as the sovereign (jun) herb, primarily targeting the pattern of temporary heat imbalance. Tofu (Dou Fu) is cool in nature and sweet in flavor, entering the Spleen (SP), Stomach (ST), and Large Intestine (LI) meridians. It can help soothe the middle and promote qi, while supporting the body’s natural cooling and blood circulation. Thus, it both assists Gypsum in supporting the body’s heat discharge and protects the Spleen and Stomach, preventing Gypsum’s extreme cold from affecting the middle yang.

Dried Chinese cabbage (Brassica rapa subsp. pekinensis) is neutral in nature and sweet in taste; it enters the Lung (LU) and Stomach (ST) meridians. It has the actions of helping to moisten the Lung, support intestinal comfort, nourish the Stomach, and support fluid balance. Fresh ginger (Zingiber officinale Roscoe) and honeyed jujube (Fructus Jujubae) are used as adjuvants: they both help balance the cold nature of Gypsum Fibrosum, harmonize the various ingredients, and improve the flavor. The entire formula is meticulously composed, combining cooling with moistening and purging with tonifying, so that temporary heat imbalance is supported without affecting the body’s upright qi, and body fluids are restored without creating cloying stickiness.

Formula Analysis and Key Points of Compatibility

The dosage of gypsum (Gypsum Fibrosum) is typically 30–60 g, tofu (Glycine max [tofu]) 200–300 g, dried Chinese cabbage (Brassica rapa subsp. pekinensis [dried napa cabbage]) 30–50 g, fresh ginger (Zingiber officinale [ginger]) 3–5 slices, and candied jujube (Ziziphus jujuba [candied dates]) 2–3 pieces. The gypsum should be decocted first to facilitate the extraction of active constituents, while the tofu and dried cabbage are added later to the soup and simmered to preserve their nutrition and texture. It is important to note that raw gypsum (crude gypsum) must be used instead of calcined gypsum, because its cooling support primarily derives from the crystalline form of calcium sulfate dihydrate.

Suitable Population

This medicated diet is especially suitable for individuals with a temporary internal heat pattern, commonly presenting with a red face and bloodshot eyes, dry mouth with a preference for cold drinks, dry stools, scanty yellow urine, and a red tongue with yellow coating. For example, those in the early stage of wind-heat common cold accompanied by sore throat, or those experiencing gum swelling and pain or mouth ulcers after consuming spicy foods, can help maintain comfort by drinking this soup.

Additionally, workers frequently exposed to high-temperature environments, teachers whose throats become dry and irritated from prolonged speaking, young people prone to internal heat due to a preference for spicy and greasy foods, as well as elderly individuals and children during dry seasons, are all suitable candidates for using this soup as a preventive and regulating support. However, care should be taken to space out consumption from other cold-natured foods or ingredients to avoid accumulation of cold nature.

Contraindicated Populations

Since Gypsum (Gypsum Fibrosum) is greatly cold in nature, and both tofu (Doufu) and dried cabbage (Bai Cai Gan) are also cool in property, individuals with Spleen and Stomach Yang Deficiency (Pi Wei Xu Han) should use with caution or avoid consumption. Such patients often present with epigastric cold pain, preference for warmth and pressure, loose stools, and cold extremities. Improper intake of this soup may aggravate the burden on the spleen and stomach, leading to abdominal pain, diarrhea, and other discomforts.

In addition, those with constitutional yang deficiency or internal exuberance of cold-damp should not take it. Pregnant women should decide whether to use it under a physician’s guidance. Breastfeeding women also need to be cautious to avoid affecting the infant through breast milk due to its cold nature. Furthermore, individuals allergic to soy products or Chinese cabbage should avoid consumption. While taking this soup, one should not concurrently take tonifying Chinese herbs or warming-drying foods, as this may affect the efficacy or cause adverse reactions.

Proportion of Ingredients in the Formula

Gypsum (Gypsum Fibrosum, raw) 30–60 g, tofu (preferably tender) 200–300 g, dried Chinese cabbage 30–50 g, fresh ginger (Zingiber officinale) 3–5 slices (approx. 10 g), honey jujube (Ziziphus jujuba) 2–3 pieces (approx. 15 g), and salt (to taste, added at the end). The above amounts are suggested for 2–3 servings and may be adjusted according to the number of people and individual constitution.

When purchasing gypsum (Gypsum Fibrosum) at a Chinese herbal pharmacy, request unprocessed (raw) gypsum and ask the staff to crush it into coarse granules to facilitate the extraction of active constituents during decoction. For dried Chinese cabbage, select specimens with a natural color and no signs of mold; soak in clean water in advance until soft, then rinse thoroughly. For tofu, it is best to choose brine-set tofu or gypsum-set tofu (approximately 150 mg of calcium per 100 g), which works synergistically with the gypsum in the soup to enhance calcium supplementation.

Preparation Method

First step: Place the dried Chinese cabbage (白菜干) in a bowl, add enough warm water to soak for about 30 minutes until fully softened. After it becomes soft, squeeze out the excess water and cut into sections about 5 cm long, then set aside. Cut the tofu into thick cubes of about 2 cm, soak in lightly salted water for 10 minutes to increase firmness, then remove and drain well.

Step 2: Place the raw Gypsum (Gypsum Fibrosum) into a gauze bag and tie the opening securely. Put the bag into a clay pot, add 2000 ml of water, and bring to a boil over high heat. Then reduce to low heat and simmer for 30 minutes, allowing the active components of the Gypsum to fully dissolve into the water. This step is crucial and cannot be omitted or shortened.

Step 3: Place the rehydrated dried Chinese cabbage, tofu cubes, sliced fresh ginger, and honey dates together in a clay pot. Bring to a boil over high heat, then reduce to low heat and simmer, maintaining a gentle boil, for 40-50 minutes. Avoid opening the lid frequently to prevent loss of aroma. Once the soup turns slightly white, the dried cabbage is tender, and the tofu develops honeycomb pores, remove and discard the gypsum herb sachet.

Step 4: Add an appropriate amount of table salt for seasoning, stir well, then turn off the heat. This soup should be taken warm, but be careful not to burn the mouth or esophagus. For a lighter flavor, add little or no salt. Leftover soup can be stored in the refrigerator, but it is recommended to consume within 24 hours.

Tips for Taking

1. Gypsum, Tofu, and Dried Vegetable Soup should be consumed in divided doses during the daytime, with each serving being a small bowl (approximately 200–250 ml), 2–3 times daily. Continuous consumption should generally not exceed 3 days to avoid excessive coldness. If discomfort does not improve, seek professional advice promptly.

2. This decoction is best consumed about one hour after meals, and should be avoided on an empty stomach. When the stomach is empty, gastric acid concentration is higher, and cold-natured substances can directly irritate the gastric mucosa, causing discomfort. For those with weak Spleen and Stomach function, the amount of Zingiber officinale (ginger) may be appropriately increased to moderate its cold nature.

3. During the period of consumption, maintain a light diet, avoiding spicy, greasy, and deep-fried foods that may promote heat. Also refrain from consuming warm-dry foods such as lamb and dog meat. It is recommended to pair with plenty of fresh vegetables and moderate amounts of fruit to help support the body’s natural cooling and nourishing processes.

4. If used for helping comfort sore throat or oral sensitivity, allow the decoction to cool to a warm temperature, then gargle with it for a moment before swallowing slowly. Let the liquid remain in the oral cavity and throat area for a longer time to achieve a better local cooling effect. However, note that this should not replace professional attention; if symptoms are severe, seek professional advice promptly.
