Hair growth is a concept of traditional Chinese medicine. Chinese medicine has broad and narrow definitions of hair. Broadly speaking, hair products are foods with the same nature and taste as some diseases. After eating, it may aggravate the imbalance between yin and yang and aggravate or induce some diseases, including fever, wind, damp heat, chills and blood deficiency.

In a narrow sense, hair products are foods that can poison and help fire, and may induce old diseases and add new diseases. In real life, people generally refer to hair in a narrow sense.

Mutton is a kind of wool in a broad sense and belongs to fever. This is because mutton itself is warm and sweet, enters the spleen and kidney meridians, and has the effects of nourishing qi and blood and helping Yuanyang. It is more suitable for patients with anemia, postpartum or post-illness deficiency of both qi and blood and deficiency of cold. However, people with yin deficiency and excessive fire will eat it, which will contribute to intense heat, damage body fluids, lead to fever, thirst, constipation, etc., and may also make some fever relapse or aggravate. Therefore, people with strong yang or fire due to yin deficiency should be careful to eat mutton, and patients with hypertension should also avoid eating it.

In fact, hair that is really harmful to the human body does not exist. In a healthy state, all foods that are not allergic and healthy can be eaten. Once you get sick, you should pay attention to the doctor's advice and avoid eating food with the same taste as your illness, so as not to aggravate your illness.
