Between the food that nourishes and the medicine that treats, the Chinese tradition has always recognised a third category: the food that treats. Shí Liáo (食疗), literally “the dietetics that heals”, names this art of prescribing foods as one prescribes remedies: not in the pharmaceutical sense, but in the sense that certain foods, at a precise dose and in a precise context, carry genuine therapeutic power. It is the founding concept linking kitchen to pharmacopoeia, and it has its own lexicon entry.
Shi Liao: the art of nourishing and treating through food
Shí Liáo is not “eating healthily”: it is a dietary prescription. The difference lies in intention and precision. One does not eat ginger “because it is good for you”: one takes it, warm and measured, because the picture calls for dispersing Cold. One does not consume mushrooms “for health”: one chooses them because their energetic profile matches the terrain.
The tradition distinguishes three levels of substances: everyday food (nourishes, little risk, daily use), the food-medicine (treats, with dose and context, occasional or regular use), and the pharmacopoeia remedy (treats, high potency, practitioner’s prescription). Shí Liáo inhabits the middle zone.
The food / medicine frontier: energetic and legal
The frontier between food and food-medicine does not lie in the nature of the substance: it lies in its use. The same ginger is a condiment in the soup and a remedy in the decoction. What makes the difference is the dose, the preparation, the duration, and above all the relevance to the picture: a food-medicine only makes sense if it matches the terrain being treated.
The energy of the substance, its thermal nature, its flavour, its tropism: everything that makes the everyday food also makes the food-medicine, but concentrated. Which is why prescribing these foods is never trivial: their potency is real, and it can work against a terrain that is not theirs.
The five categories: spices, mushrooms, tonic berries, seeds, marine produce
The course and the tradition group food-medicines into five broad families, each with its own logic:
Spices and aromatics: ginger, cinnamon, pepper, clove, cardamom. Their pungent, hot nature makes them the dispersants par excellence: they drive out cold, move circulation, wake the digestive fire. This is the most accessible, most everyday category of Shí Liáo.
Medicinal mushrooms: shiitake, reishi, maitake, yunzhi. A whole family that tonifies: the Qi, the Blood, deep immunity. Medicinal mushrooms warrant their own article: their culinary use is simple, their terrain power considerable.
Tonic berries and fruits: goji berries, jujubes, longans, mulberries. Small but concentrated: they nourish Blood, Yin, Jing. Their sweetness is a vehicle of gentle tonification.
Seeds and nuts: black sesame, pumpkin seeds, walnuts, almonds, sunflower seeds. The family of oils and “concentrated” substances: they nourish Yin, Jing, the brain.
Marine produce: seaweeds (kelp, wakame, nori), oysters, shellfish, small whole fish. The salty flavour that softens masses, drains Dampness, nourishes the Kidney.
When food becomes medicine: potency and precautions
Prescribing a food-medicine calls for the same vigilance as prescribing a remedy, at a lower but real dose. Three precautions structure its use:
The potency exists. A poorly chosen food-medicine can worsen: warming a hot terrain, moistening a damp terrain, dispersing a depleted one. The reading of the terrain always precedes the prescription.
Interactions exist. Certain food-medicines interfere with treatments (grapefruit is the famous case, but not the only one); any therapeutic use of a potent food is discussed with the doctor or pharmacist when a treatment is ongoing.
Duration matters. A food-medicine is not a daily food: it is taken at a defined dose, for a defined time, then reassessed. The food that treats at the right dose and context becomes the food that unbalances in excess or in permanence.
The French legal framework: advice, never pharmaceutical prescription
In France, Chinese dietetics is terrain advice, not pharmaceutical prescription: food-medicines fall under nutritional guidance and support, never medical prescription in the legal sense. The practitioner who advises a Shí Liáo is not prescribing a drug: they are recommending a food in a context.
This legal frontier is also one of common sense: for any serious health problem, any ongoing treatment, any pregnancy or particular situation, food-medicine advice is given with the treating physician, not in their place.
