Crocus sativus is a well-known "Tibetan medicine" at home and abroad, which is collected from the alpine region above 5000 meters above sea level. Its medicinal effects are peculiar, especially for promoting blood circulation and nourishing blood. According to Compendium of Materia Medica, crocus sativus can "promote blood circulation, control depression and treat fright". Crocus sativus has the functions of dredging meridian passage, removing blood stasis, removing blood stasis and swelling, cooling blood and detoxicating, relieving depression and calming the nerves. Taking it for a long time can make people feel happy and improve human immunity in an all-round way. Modern pharmacological research has proved that it is effective in improving myocardial blood supply and oxygen supply. Crocus sativus contains many glycosides, which can obviously increase the blood flow of coronary artery.

In recent years, scientists have found that crocin, crocin aldehyde, crocin and crocin in the stamens of crocus sativus have strong anticancer activity. In particular, it has a strong inhibitory effect on blood cancer cells, papillary carcinoma, squamous cell tumor and soft tissue sarcoma. Its anticancer mechanism is to inhibit the synthesis of DNA and RNA in cancer cells, the activity of cellular protein kinase and the expression of proto-oncogene, and the toxicity of carcinogens such as benzopyrene and 12-O- 14 acylphosphinone-13 acetate (TPA), thus inhibiting the formation of tumors at the molecular level. The semi-lethal dose of its cancer cells is 0.8 ~ 2 microns, and its toxicity is far less than that of retinoic acid. Therefore, anti-cancer active substances such as crocin will become one of the most ideal anti-cancer drugs in 2 1 century.

The unique magical effect of crocus sativus is widely used by Chinese and foreign medical circles to prevent and treat cerebral thrombosis, vasculitis, myocardial infarction, blood deficiency, irregular menstruation, postpartum congestion, general pain, traumatic injury, neurasthenia and panic disorder.
