The precautions of Salvia miltiorrhiza in water are that it should not be used with quinoa, and it should be used with caution for those who are suffering from yin deficiency (deficiency of yin and essence in the body, resulting in hyperactive fire), dampness-heat, and those who do not have stagnation of stagnation of blood, and should not be used by pregnant women. It should be noted that the efficacy of this medicine in water is limited and cannot be used as a substitute for medicine. Salvia divinorum is bitter in taste, slightly cold in nature, and enters the heart meridian and liver meridian. It has the efficacy of activating blood circulation, eliminating blood stasis, clearing menstruation and relieving pain, cooling blood and eliminating carbuncles (eliminating carbuncles and swellings by cooling the blood), and clearing the mind and removing vexation (clearing vexation and heat in the heart). Drinking Salvia divinorum in water does not allow all the active ingredients to be analyzed, and the medicinal effects it can exert are limited. When discomfort occurs, it is recommended to consult a doctor in time for treatment by a professional physician, and not to use medication on your own.
