Glutamine, or Glutamine Tablets, belongs to Western medicine, while Yin deficiency and fire (deficiency of Yin and essence in the body, and the emergence of hyperactive fire) belongs to the concept of traditional Chinese medicine, so the claim that Glutamine treats Yin deficiency and fire is inaccurate. Glutathione tablets are mainly used for neurosis, premenstrual tension syndrome, menopausal syndrome sedation and sleep aid. Taking it may lead to adverse reactions such as nausea, vomiting, dry mouth, fatigue, rash, breast swelling, excessive oil secretion, hair loss, weight gain, etc., but all of them can disappear after stopping the drug. Use with caution in patients with gastric and duodenal ulcers. Although the symptoms of yin deficiency and fire exuberance (deficiency of yin and essence in the body, resulting in hyperactive fire), such as irritability and insomnia, hot flashes (a burst of fever), palpitations (rapid heartbeat, often accompanied by panic), are similar to the indications of Gulvestrol tablets for neurosis, premenstrual tension syndrome, etc., the two can not be equated, so the claim that the Gulvestrol tablets are used to treat yin deficiency and fire exuberance is inaccurate. Glutathione tablets need to be taken under the guidance of a professional doctor. If there is any discomfort, consult a doctor promptly.
