Introduction to Medicinal Cuisine
Celery and Raw Coix Seed Soup is a classic medicinal diet originating from Lingnan folk tradition, combining the dual effects of clearing heat and draining dampness. It features common celery (also known as Chinese celery or medicinal celery) and raw Coix seed (semen coicis) as the main ingredients, prepared with a small amount of seasoning. This soup has a refreshing taste, with the unique fragrance of celery and the mild cereal aroma of Coix seed. It can be served as a daily side dish soup while also offering significant health-preserving and regulating benefits.
Coix seed (*Coix lacryma-jobi* var. *ma-yuen* / Job’s tears) is classified as a superior herb in the *Shen Nong Ben Cao Jing* (Shen Nong’s Classic of the Materia Medica). Physicians throughout the ages have regarded it as cool in nature, sweet and bland in taste, with the ability to fortify the spleen, percolate dampness, clear heat, and expel pus. Celery (*Apium graveolens* / celery), on the other hand, is cool in nature, sweet and acrid in taste, and enters the Liver (LR), Stomach (ST), and Lung (LU) channels. It has the effects of pacifying the liver, clearing heat, dispelling wind, and disinhibiting dampness. When used in combination, the former focuses on clearing and disinhibiting damp-heat in the lower *jiao*, while the latter excels at clearing and resolving stagnant heat in the liver channel. They complement each other, making the formula’s action of clearing heat and disinhibiting dampness more balanced, gentle, and sustained. This soup is especially suitable for consumption during the transition from spring to summer or the long summer period when damp-heat is heavy. It effectively helps the body expel internal dampness and clear stagnant heat.
Efficacy of Medicinal Diet
The main effects of Celery and Raw Coix Seed Decoction are focused on two aspects: clearing Heat and draining Dampness, and calming the Liver and descending Turbidity. Raw Coix Seed promotes the elimination of excess fluid and turbid dampness from the body, thereby alleviating symptoms such as heavy limbs, mild lower extremity edema, and sticky, difficult stools caused by internal retention of water-dampness. Celery, on the other hand, clears Liver Heat and soothes Liver Qi, helping to improve discomforts like facial flushing, irritability, and dizziness due to Liver Fire flaring upward.
From a nutritional perspective, celery (Apium graveolens) is rich in apigenin, dietary fiber, and various vitamins, while raw coix seed (Semen Coicis) is abundant in coixenolide, coixol, and B-complex vitamins. Apigenin helps dilate blood vessels and supports blood pressure regulation, whereas coixenolide is believed to aid in modulating body metabolism. Therefore, this soup can provide a mild, supportive regulating effect for young and middle-aged individuals presenting with blood pressure fluctuations, elevated blood lipids, and scanty dark urine due to Damp-Heat internally accumulated or Liver Yang ascending hyperactivity.
Core Regulation Direction
This formula is especially suitable for daily regulation of individuals with a Damp-Heat constitution or Liver Heat constitution. So-called “Damp-Heat constitution” commonly presents with: oily facial skin, acne, bitter taste and dry mouth, yellow and greasy tongue coating, dark yellow urine, and sticky, difficult stools. So-called “Liver Heat constitution” commonly presents with: irritability, distending pain in the hypochondria, dry mouth and throat, dizziness, and restless sleep. Celery and Raw Coix Seed Decoction (Qincai Sheng Yiren Tang) can simultaneously address the regulatory needs of both constitutional tendencies.
The Role of Traditional Chinese Medicine
Within the theoretical framework of Traditional Chinese Medicine, the mechanism of action of Celery and Raw Coix Seed Decoction (芹菜生薏仁汤) can be understood from two dimensions: “nature, flavor, and meridian tropism” (性味归经) and “compatibility synergy” (配伍增效). Raw Coix Seed (Coix lacryma-jobi L. var. ma-yuen, Semen Coicis) has a sweet (甘) and bland (淡) flavor, a slightly cold nature (微寒), and enters the Spleen (SP), Stomach (ST), Lung (LU), and Large Intestine (LI) meridians. Its sweetness can tonify the Middle Burner (补中), its blandness can promote dampness drainage (渗湿), and its coldness can clear heat (清热). Thus, it strengthens the Spleen without hindering dampness, and drains damp-heat without damaging Yin. Celery (Apium graveolens L.) has a sweet (甘) and acrid (辛) flavor, a cool nature (凉), and enters the Liver (LR), Stomach (ST), and Lung (LU) meridians. Its acridity disperses (散) and its coolness clears (清), enabling it both to disperse wind-heat from the Liver Meridian, and to clear and resolve Stomach heat from the Yangming (阳明) Meridian.
The combination of these two ingredients functions as follows: celery focuses on “clearing”—clearing liver heat and dispersing stagnant fire; raw Coix seed focuses on “draining”—draining damp-heat and expelling turbid qi. One clears and one drains, allowing heat to be resolved internally and dampness to descend externally, together achieving the effect of clearing both dampness and heat. Moreover, this pairing accords with the TCM principle that “in treating dampness, failure to promote urination is not a proper treatment,” as the diuretic action of raw Coix seed provides an outlet for pathogenic damp-heat. It should be noted that raw Coix seed (生薏仁) is used here rather than stir-fried Coix seed (炒薏仁), because raw Coix seed has stronger heat-clearing and damp-draining properties, making it more suitable for constitutions with predominant damp-heat; stir-fried Coix seed, on the other hand, strengthens the spleen but reduces heat-clearing efficacy, and the nature of the two preparations differs accordingly.
Detailed Explanation of Nature, Flavor, and Meridian Tropism
Celery (Apium graveolens) enters the Liver Meridian and can pacify Liver Yang, providing effective relief for dizziness, distending headache, flushed face, and red eyes caused by Liver Yang Rising. Raw Coix Seed (Coix lacryma-jobi var. ma-yuen, commonly known as Job’s tears) enters the Spleen and Stomach Meridians, fortifies the Middle Jiao, and dispels dampness-turbidity, thereby improving poor appetite, epigastric and abdominal fullness, and loose stools due to Dampness Encumbering the Spleen and Stomach. One disperses and the other promotes transportation, jointly maintaining the harmonious balance of Liver and Spleen functions.
Indications
Celery and Raw Coix Seed Decoction (芹菜生薏仁汤) is most suitable for daily consumption by the following groups: First, individuals with a Damp-Heat constitution, presenting with oily facial and scalp skin, tendency to develop acne, bitter taste and sticky sensation in the mouth, yellow and greasy tongue coating, sticky stools or scanty dark urine; second, those with Liver Heat or Liver Yang Hyperactivity, manifesting as irritability and anger, unstable sleep, dizziness and blurred vision, elevated blood pressure, red and swollen eyes; third, people who during the plum rain season or long summer damp-heat climate feel a heavy and sluggish body, low spirits, loss of appetite, and thirst without desire to drink.
Furthermore, for middle-aged and young individuals who experience dyslipidemia and significant blood pressure fluctuations due to high work stress and a diet rich in fatty, sweet, and heavy flavors, this soup can serve as one of the low-fat, light dietary regulation options. For elderly individuals presenting with mild Damp-Heat or Liver Heat signs, appropriate consumption under the guidance of a physician can also help improve related symptoms. It is noteworthy that this soup is relatively cool in nature. It is most effective for individuals with an Excess Heat constitution, while those with a Deficiency Cold constitution should use it with caution.
Contraindicated populations
The following individuals should avoid or exercise caution when consuming Celery and Raw Coix Seed Soup (Qín Cài Shēng Yì Rén Tāng): 1. **Spleen-Stomach Deficiency Cold (Pí Wèi Xū Hán)**. Both raw Coix Seed (Yì Rén) and Celery (Qín Cài) are cool in nature. In individuals who typically present with cold pain in the epigastrium that is relieved by warmth, loose stools, aversion to cold, and cold extremities, consumption of this soup may aggravate deficiency-cold symptoms, leading to abdominal discomfort or diarrhea. 2. **Pregnant women**. Raw Coix Seed (Yì Rén) has a stimulating effect on uterine smooth muscle. Traditional Chinese Medicine holds that Coix Seed (Yì Rén) carries a risk of causing miscarriage (huá tāi). Therefore, pregnant women—especially during the first trimester—should strictly avoid consuming this soup.
Third, women during menstruation. During the menstrual period, especially those with deficiency-cold dysmenorrhea presenting as cold pain in the lower abdomen, scanty and pale menstrual flow, such cooling soups should be avoided to prevent cold congealing blood stasis and worsening of dysmenorrhea. Fourth, individuals with hypotension. Celery has a certain auxiliary antihypertensive effect; those with already low blood pressure may experience symptoms such as dizziness and fatigue after consuming large amounts, leading to hypotensive reactions. Fifth, individuals taking diuretics or antihypertensive medications. It is recommended to consult a physician first to prevent additive drug effects that could result in electrolyte imbalance or excessively low blood pressure.
Ingredient formula proportions
Here is a precise recipe for one serving (approximately 500 ml of finished soup): Fresh celery with leaves (Apium graveolens) 150 g, raw Coix seed (Coix lacryma-jobi var. ma-yuen) 50 g, lean pork (or chicken breast) 80 g, fresh ginger (Zingiber officinale) 3 slices (about 6 g), and salt to taste (about 1–2 g, added at the end for seasoning). For a vegetarian version, omit the meat and replace it with 3 dried shiitake mushrooms (Lentinula edodes, about 10 g, pre-soaked) and 100 g of tofu, which will also enhance the umami and nutritional value of the soup.
The dosage of raw Coix seed (Semen Coicis, 50g) is carefully calibrated: it is sufficient to achieve a significant effect of clearing heat and draining dampness, without being overly cold due to excessive quantity. Celery (Apium graveolens) is used with its leaves, as the active constituents are often more concentrated in the leaves than in the stalks, thereby enhancing its ability to clear heat and pacify the liver (ping gan). Fresh ginger (Zingiber officinale) is added to temper the cooling nature of the celery and raw Coix seed, making the soup more balanced in property. At the same time, ginger helps to remove fishy odors, enhance aroma, and stimulate appetite.
Preparation Method
Step 1: Preparation. Rinse raw Coix seeds (Coix lacryma-jobi var. ma-yuen) twice with clean water to remove impurities, then place in a bowl and soak in sufficient water for at least 2 hours (if time is limited, a minimum of 40 minutes). Soaking allows the seeds to fully absorb water and swell, reducing subsequent cooking time while facilitating the extraction of active constituents. Remove any old leaves from celery (Apium graveolens), wash off grit, and keep the stalks and leaves separately—cut the stalks into approximately 3 cm segments. Rinse and slice lean pork, then marinate with a small amount of cooking wine and salt for 10 minutes to remove any unpleasant odor.
Step 2: Precooking the Coix Seed (Yì Yǐ Rén). Pour the soaked raw Coix seed together with the soaking water into a stockpot (if the soaking water appears cloudy, replace with fresh water). Add additional water to reach a total volume of approximately 800 ml. Cover with a lid, bring to a boil over high heat, then reduce to medium-low heat and simmer for 30 minutes, until the Coix seed is fully expanded, soft and glutinous, and the decoction turns milky white. This step is crucial—only thoroughly cooked Coix seed can fully release its therapeutic constituents and gelatinous substances into the decoction.
Step 3: Add the main ingredients. Place the cut celery segments, celery leaves, sliced fresh Zingiber officinale (ginger), and the marinated meat slices into the pot. Continue to cook over medium-low heat for 10 minutes. Note that celery should not be cooked too long to preserve its bright green color and crisp texture, while also avoiding excessive damage to its active constituents. When the meat slices change color, the celery becomes tender, and the soup becomes aromatic, season with an appropriate amount of table salt, stir evenly, then turn off the heat. According to personal preference, add a few drops of sesame oil to enhance the aroma. Serve warm.
Drinking Tips
First, timing and frequency of consumption. Celery and Raw Coix Seed Decoction (Apium graveolens & Coix lacryma-jobi var. ma-yuen) is recommended to be taken warm, either one hour after lunch or one hour before dinner, 2–3 times per week. Continuous consumption should not exceed two weeks. For those with severe Damp-Heat symptoms, it may be taken for 3–5 consecutive days, followed by a two-day interval before resuming. Once symptoms subside, reduce the dosage or discontinue use to avoid prolonged intake damaging Spleen-Stomach Yang Qi. It is not recommended to take on an empty stomach to prevent cold-natured irritation to the gastrointestinal tract.
Second, regarding seasoning and pairing. This soup is primarily light and based on its original flavors; strong pungent and hot-natured substances such as chili pepper and Sichuan pepper should not be added, as they may interfere with the effect of clearing heat and draining dampness. It can be consumed together with spleen-fortifying ingredients such as Shan Yao (Chinese yam) and Fu Ling (Poria) to enhance the spleen and stomach’s ability to transport and transform damp turbidity. During the period of consumption, it is recommended to reduce intake of greasy, sweet, and raw-cold foods, as these may promote dampness and generate heat, contradicting the therapeutic direction of the medicinal diet.
Third, ingredient handling and storage. Raw coix seed (Coix lacryma-jobi var. ma-yuen) should be stored in a cool, dry place to prevent moisture and mold. Fresh celery (Apium graveolens) after purchase can be wrapped in a plastic bag and refrigerated, ideally used within three days. If the prepared soup cannot be consumed in one sitting, strain out the dregs and refrigerate, but do not exceed 24 hours, and it must be brought to a full boil again before drinking to prevent bacterial growth. It is not recommended to reheat more than twice, lest the taste and therapeutic effects diminish.
