It is possible to have an increase in blood pressure after taking Liu Wei Di Huang Wan because the main effect of Liu Wei Di Huang Wan is to nourish yin and tonify the kidneys. The composition of the drug includes Shu Di, Shan Yu Pei, Mudan Pi, Shan Yao, Fu Ling and Ze Xie, which have a certain nourishing effect, so patients who do not have kidney yin deficiency are prone to blood pressure fluctuations after taking it. Patients with high blood pressure should take Liu Wei Di Huang Wan under the guidance of a doctor. The three medicines are used to nourish the liver, spleen and kidneys, so they are called the three tonics. However, the dosage of Shu Di is the sum of Shan Yu Pei and Shan Yao, so this formula still mainly nourishes kidney yin. At the same time, it is combined with Ze Xie to relieve dampness and drain turbidity, and to prevent Shu Di from being overly nourishing. The three herbs together become a triple diarrhea, which can penetrate dampness, clear deficiency heat, and calm its bias to treat the symptoms.
