What you call heat should be referring to the four qi of medicine, that is, warm, hot and cold. These are two extremes, but four groups of adjectives with different degrees.

Korean ginseng is actually a red ginseng. Some properties and flavors are similar to red ginseng, and its functions and indications are similar. However, both red ginseng and Korean ginseng are warm in nature, and there is no such thing as heat.

If the medicinal materials are warm in nature, they will not cause internal heat as long as the dosage is not exceeded and the medicine is not taken according to the body constitution.
