Can Dang Gui and Huang Qi be steeped together in water for consumption?
Generally speaking, Angelica sinensis (Dang Gui) and Astragalus (Huang Qi) can be steeped together in water for consumption, but it is important to drink them in moderation. The detailed explanation is as follows:

Huang Qi is particularly effective at replenishing qi, especially spleen and lung qi, enhancing the body's immunity and improving symptoms of qi deficiency. Dang Gui excels at nourishing blood, regulating heart and liver blood, and significantly improving symptoms such as pallor and dizziness caused by blood deficiency. When used together, they can both replenish qi and nourish blood, making them suitable for individuals with deficiency of both qi and blood.
Dang Gui has the effect of promoting blood circulation and regulating menstruation, effectively alleviating irregular menstruation and dysmenorrhea caused by blood stasis. Huang Qi enhances the blood-activating effect of Dang Gui, facilitating smoother menstrual flow. Together, they help improve overall immunity and prevent diseases. Although steeping Angelica sinensis and Astragalus together offers multiple health benefits, it is important to consume them in moderation. Excessive consumption may lead to symptoms such as heatiness and indigestion.
Pregnant women, nursing mothers, children, and other special populations should use them under the guidance of a physician. Individuals allergic to Angelica sinensis or Astragalus should avoid consumption. While consuming Dang Gui and Huang Qi water, it is advisable to avoid eating spicy, greasy, raw, or cold irritating foods, as these may interfere with the herbal effects.
