In Traditional Chinese Medicine, it is believed that during winter, the body's Yang energy is stored internally. Eating radish can help clear internal heat and turbid Qi that accumulates in the body. As the weather is cold in winter, people tend to favor warming and nourishing foods, which can lead to excessive richness, internal damp-heat, or 'fire'. Eating radish can counteract these effects.
In clinical practice, many patients ask if they can eat radish while taking Chinese herbal medicine. This depends on the therapeutic purpose of the herbal formula and the specific herbs within it. The radish most people ask about is the white radish. White radish is sweet and cold in nature, with the effects of promoting Qi circulation and relieving constipation. Healthy individuals and some patients with abdominal bloating or difficult bowel movements can benefit from eating radish (it can be boiled, stir-fried, stewed, or even juiced) to regulate Qi, clear internal heat, and help ensure the smooth flow of Qi throughout the body.
When taking highly nourishing Chinese medicine, especially formulas that tonify Qi deficiency, the patient's central Qi is weak and requires supplementation from the herbs. In this case, eating a small amount of radish is generally not a problem, but consuming too much might reduce the medicine's efficacy. Furthermore, ginseng should not be taken with radish. For specific advice, it is best to consult a doctor.
