Astragalus is an herbal tonic that has many benefits and everyone is willing to take it to make tea and drink. But there are times when astragalus can be used and not used, did you know that? Astragalus can nourish the qi and strengthen the spleen, benefit the guard and strengthen the table, raise the yang and lift the trap, and can diuretic and reduce swelling. When used properly, it can save lives; when used improperly, it may produce bad effects. Astragalus has been proven by modern pharmacological research: it has both an elevating effect and an antihypertensive effect. So our hypertension patients, in the choice of astragalus tea drinking must know: astragalus is a double-edged sword, accidentally your blood pressure like a small train whirring up. Astragalus is reported to raise blood pressure in small doses, it can increase the heart’s ejection volume and raise blood pressure by strengthening the heart. Older people have poor vascular elasticity, increasing the heart ejection will make the systolic blood pressure rise more significantly. And how much is considered small in small doses, there is not yet a unified opinion, so our hypertensive patients must not take their own advice to supplement Astragalus, but listen to the advice of the doctor, you can use other herbs instead, the doctor can make specific guidance according to your cold and heat deficiency. As the dose of Astragalus increases, the diuretic and decongestant effect of Astragalus is manifested. Diuresis reduces blood volume and just as the water level in a river drops and the danger of dam collapse is reduced, our blood pressure also drops with this outgoing water. So astragalus in high doses can lower blood pressure. Just as small doses raise blood pressure, there is no definitive conclusion as to what the standard large dose needed to lower blood pressure is, so it is better not to take it for granted yourself and try oh.
