There are some individual differences in how long to take Rhodiola rosea in advance and its specific therapeutic purpose. Rhodiola Rosea is a proprietary Chinese medicine with a slow onset of action, mainly benefiting Qi and blood, tonifying the kidneys and improving immunity. In case of low menstrual flow and menopause due to blood stasis and obstruction, it can be treated by taking Rhodiola Rosea. Usually, this drug needs to be taken immediately after ovulation, i.e. about 10-13 days before menstruation, to achieve the best therapeutic effect. In addition, Rhodiola rosea can also relieve symptoms such as shortness of breath and vomiting, dizziness and weakness caused by hypoxia at plateau, which can enhance the non-specific resistance of the body to harmful stimuli and help improve the body’s adaptability to hypoxic stimuli. For people who are new to the plateau or frequent residents of the plateau, it is better to start taking it 10-15 days in advance when they return to the plateau from other places. In addition, if patients experience allergic symptoms such as rash, itching and other allergic reactions while taking the medication, it is recommended that the medication be discontinued immediately.
