Saffron is suitable for long-term adherence, and the time to drink the medicine is divided into various conditions. Saffron is an invigorating type of medicine that has the effect of invigorating blood and dispersing nodules, which is good for patients with blood deficiency in the body and dysmenorrhea. It is generally recommended that each time you take 5-8 filaments soak 3-4 cups of water, you can drink three days to stop a day; in a small amount, you can drink once a day; if you are not too comfortable with drinking saffron, you can consider taking it once every two or three days. When taking the juice can be taken by direct decoction, but also can be repeatedly brewed with boiling water 3-4 times before taking. In addition, it should be noted that saffron should be prohibited for pregnant women, menstruating and bleeding patients. Also, for people who do not have symptoms of blood stasis, frequent use of saffron infusion is not good for health and can even lead to skin ulcers in serious cases. Therefore, saffron needs to be taken strictly in accordance with the doctor’s instructions and in a regular manner so as not to damage the health of the body.
