Tannic acid in tea can inhibit the increase of blood pressure and reduce the blood pressure of patients with hypertension. In particular, apocynum tea has a good decomposition effect on protein and fat. Polyphenols and vitamin C can lower cholesterol and blood lipids.

Dizziness and headache caused by "three highs" can be obviously relieved or eliminated by most friends 1-3 days.
Most friends will feel sleepy (some friends think it is dizziness), sleepy and listless after drinking apocynum tea for the first time. This is normal, because it has the effect of calming the nerves and helping sleep. After a period of time, the body will adjust itself and return to normal (if it has an impact on work and life, you can add green tea to neutralize it).
Some friends may have more defecation times, which is because it has a laxative effect, but only the normal defecation times increase, and they can be discharged after discharge, not diarrhea, which is essentially different. It will return to normal after a while.
Like some traditional teas, it can also promote digestion and diuresis.
Apocynum tea has a cardiotonic effect. If you drink too much at first (for example, some friends are eager to see the effect, from one cup of water to half a cup or even less than 1/4 cups, just like Chinese medicine), you may feel chest tightness and flustered. This is a normal reaction, just drink lightly and let the body gradually adapt to the adjustment process.

Which friends need to use apocynum tea with caution or drink less at first?
Pregnant women. Although there are no examples to prove that pregnant women can't drink alcohol, I haven't found any examples of pregnant women drinking alcohol for the time being. Therefore, for the sake of safety, individuals do not recommend pregnant women to drink.
Apocynum tea, a rare tea in the desert, belongs to herbal tea. Friends with spleen and stomach deficiency or physical weakness should drink less at first and let their bodies adapt slowly.
