Although angelica and astragalus in water have the effect of nourishing qi and blood, it is not recommended to take them for a long time. Although both are relatively calm in nature and have a certain effect on the regulation of qi and blood in the human body, long-term consumption may increase the burden on the liver and kidney functions of the human body, and there is a risk of drug-related damage to liver and kidney functions. If you have symptoms such as palpitations, insomnia, dizziness, tinnitus, weakness and spontaneous sweating caused by lack of qi and blood, you can drink it for two weeks and stop taking it for two weeks or take it every other day to minimize the damage to the liver and kidney functions. Patients with damp-heat or yin-deficiency fire are not recommended to take it, as it may aggravate the symptoms of damp-heat or yin-deficiency fire in the body due to the warmth of Astragalus and Angelica.
