Can patients with nephritis take Astragalus?

In general, patients with nephritis may take astragalus (Huangqi) under professional guidance during specific stages of their condition, but it should not be taken during acute flare-ups or if contraindications exist. If in doubt, it is recommended to consult a healthcare provider in advance. Detailed analysis is as follows:

If nephritis is in a chronic stable phase—without obvious acute symptoms such as significant edema or hypertension—and kidney function tests show relatively stable indicators, small amounts of astragalus may be used under professional supervision. Astragalus has the effects of tonifying qi, reinforcing the defensive system, promoting diuresis, and reducing edema. It can help improve qi deficiency, alleviate symptoms like fatigue and mild swelling, and provide supportive benefits for maintaining disease stability.

However, if nephritis is in an acute phase, accompanied by severe edema, sudden rise in blood pressure, hematuria, or rapid decline in kidney function, or if the patient has conditions such as excess heat syndrome or yin deficiency with hyperactive fire, astragalus should not be used. In these cases, the warming and tonifying nature of astragalus may exacerbate inflammatory responses or worsen symptoms, interfering with disease management. Priority should be given to standardized treatment targeting acute symptoms rather than relying on astragalus for regulation.

Patients with nephritis must undergo professional evaluation before using astragalus and should not self-prescribe or purchase it independently. During use, regular monitoring of kidney function and disease progression is essential. If any adverse reactions occur, usage should be stopped immediately and medical advice sought to adjust the treatment plan.
