Can Astragalus be taken for a long time?

After I gave birth to my baby, I was very weak. My family members heard a lot of folk remedies that they could use for me. Astragalus is a traditional Chinese medicinal material that can replenish qi and blood, so they made it into a dish to eat. But can Astragalus be taken for a long time? Because the taste is not particularly good, I doubt that Astragalus can be taken for a long time. Some of the folk remedies do not have much scientific basis. If this continues, it will have adverse effects on the body. So I would like to understand this issue.

This product is warm in nature, sweet in taste, and enters the spleen and lung meridians. It has the functions of tonifying the spleen and stomach, nourishing the lungs and replenishing qi, consolidating the exterior and stopping sweating, expelling toxins, draining pus and promoting tissue regeneration. It is a qi-tonifying medicine that must be used for people with qi deficiency. It is suitable for spontaneous sweating, long-term sores, edema, shortness of breath, susceptibility to colds and other symptoms caused by qi deficiency.

[Modern research] Astragalus contains sucrose, glucuronic acid, several amino acids, bile alkaloids, folic acid and β-sitosterol. Astragalus can strengthen the contraction of a normal heart, and its cardiotonic effect is more significant on a heart that is in a state of decline due to poisoning or fatigue. It can dilate blood vessels, improve skin blood circulation and nutritional status, and lower blood pressure. Oral or injected Astragalus preparations have been shown to have a diuretic effect, which lasts longer. Oral administration of large doses of Astragalus powder to rats can inhibit the onset of serum nephritis and delay the occurrence of proteinuria and hypercholesterolemia. Those with proteinuria recover faster than the control group. Astragalus also protects the liver and prevents the reduction of glycogen. In vitro experiments have shown that it has an inhibitory effect on Staphylococcus, hemolytic Streptococcus, Pneumococcus, Corynebacterium diphtheriae, and Shigella dysenteriae.

Studies have shown that although Astragalus has certain functions in supplementing some of the needs of the human body, it is not necessary to take it for a long time. Because after the drug has exerted its effect within a certain period of time, there is no need to continue using it. Astragalus is also such a traditional Chinese medicine, so it is not recommended to take it for a long time.
