Can Astragalus and hawthorn be steeped together in water?
Generally, Astragalus (Huangqi) and hawthorn (Shanzha) can be steeped together in water, especially suitable for individuals with qi deficiency or elevated blood lipids. However, those with excessive stomach acid or yin deficiency with internal heat should avoid this combination. Detailed explanations are as follows:

This herbal infusion is particularly appropriate for people experiencing symptoms such as fatigue due to qi deficiency, indigestion, or high blood lipid levels. Astragalus is warm in nature and helps tonify qi and strengthen the spleen, while hawthorn is slightly warm and aids digestion, resolves food stagnation, and supports healthy lipid metabolism. These two herbs do not counteract each other and when combined, their benefits complement one another. Drinking this infusion regularly in moderation can help improve overall physical condition without causing discomfort.
However, individuals with excessive stomach acid or gastric ulcers should avoid this tea, as the organic acids in hawthorn may irritate the gastric mucosa and worsen symptoms such as acid reflux and stomach pain. Additionally, people with yin deficiency and internal heat—commonly presenting with dry mouth, thirst, and潮热 (flushing or night sweats)—should also refrain from consuming it. Since Astragalus is warming in nature, it may exacerbate internal heat in these individuals.
For daily consumption, dosage should be controlled: 5–10 grams of Astragalus and 3–5 slices of hawthorn per serving are sufficient—avoid overuse. Adjust the taste according to personal preference, and always consider your individual constitution when choosing herbal remedies to maximize their benefits safely.
