Understanding the ‘Cold, Hot, Warm, and Cool’ Properties of Foods in TCM

Foods possess four properties: cold, hot, warm, and cool, also known as the “Four Qi”. Generally, we can determine the “Four Qi” of foods based on their taste, growth environment, and geographical location.

In terms of taste, foods with a stimulating flavor tend to be more pungent and warm, such as garlic, ginger, cilantro, and chili peppers. Conversely, foods that are bitter or sour are generally cold in nature, with representative examples including bitter melon (kǔguā), plums (méizi), bitter herbs (kǔcǎo), purslane (mǎchìxiàn), and dandelion (púgōngyīng). Sweet foods, which typically receive more sunlight, are mostly hot in nature, such as pomegranates (shíliú).

Regarding the growth environment, foods that grow in water are generally cold in nature, such as lotus root (lián’ǒu), kelp (hǎidài), freshwater fish (zhòngyú), and duck meat (yāròu). Foods that grow on land tend to be warm, such as chicken (jīròu), beef (niúròu), lamb (yángròu), peanuts (huāshēng), and potatoes (tǔdòu).

From a geographical perspective, fruits that grow in tropical regions are generally warm, such as mangoes (mángguǒ), lychees (lìzhī), longans (lóngan), and durians (dǔlián). In contrast, foods from temperate or northern regions are often cool, such as apples (píngguǒ), pears (lí), and persimmons (shìzi).

Foods with cold and cool properties often have effects such as clearing heat and draining fire, cooling the blood and detoxifying, nourishing yin and generating fluids, calming the liver and settling the spirit, and promoting urination and bowel movements. They are suitable for heat syndromes, clinically manifested by fever, thirst, irritability, dizziness, headache, yellow and red urine, and constipation.

Warm and hot foods have effects such as warming the middle and dispersing cold, assisting yang and benefiting qi, and promoting circulation and blood flow. They are suitable for cold syndromes, clinically manifested by a preference for warmth, fear of cold, cold limbs, no thirst, clear and frequent urination, and loose stools.

Additionally, neutral foods have the effects of tonifying qi and blood, strengthening the spleen and stomach, and nourishing the kidneys. They can be used for both cold and heat syndromes and are also beneficial for those with spleen and stomach deficiency, such as soybeans (dàdòu), corn (yùmǐ), japonica rice (jīngmǐ), yellow soybeans (huángdòu), sesame (zhīma), eggplant (qiézi), winter melon (dōngguā), pork (zhūròu), beef (niúròu), pigeon meat (gēyā), carp (lǐyú), and crucian carp (jìyú).
