There is a saying of "eighteen oppositions" in the use of traditional Chinese medicine, which refers to the incompatibility between drugs, emphasizing the drug relationship of increasing toxicity and decreasing efficacy, and there are also taboos between medicine and food.

According to the theory of traditional Chinese medicine, radish is pungent, sweet and cool, and has the functions of promoting digestion, reducing qi, resolving phlegm, stopping bleeding and diuresis, while ginseng is sweet and slightly warm, which is a good product for invigorating vitality, spleen and lung. Both of them are taken together, and the effect of letting down the qi of radish is just the opposite to that of ginseng, which will counteract or even offset the tonic effect of ginseng. Therefore, it is reasonable to "take ginseng and not eat radish".

Extended data:

When taking other tonics or tonics, such as Radix Codonopsis, Radix Astragali, Rhizoma Atractylodis Macrocephalae, Rhizoma Dioscoreae, Radix Rehmanniae Preparata, etc., radish should not be eaten. On the other hand, if radish is taken with drugs such as regulating qi, promoting digestion and resolving phlegm, its medicinal properties are consistent, which is beneficial and harmless. Radish does not have adverse effects with all traditional Chinese medicines, and the key point depends on whether their medicinal properties are antagonistic or compatible.

Radish will produce thiocyanic acid, an antithyroid substance. If a large number of fruits such as oranges, apples and grapes are eaten at the same time, flavonoids in fruits will be transformed into thiocyanic acid that inhibits thyroid function after bacterial decomposition in the intestine, thus inducing goiter. Therefore, don't eat fruit after eating radish.
