First, patients with kidney deficiency are not suitable for taking poria cocos. For example, poria cocos is diuretic, so this advantage may just be a disadvantage for patients with kidney deficiency, so patients with kidney deficiency should never take poria cocos. The reason is that patients with kidney deficiency have poor kidneys, so there may be some problems of frequent urination and urgency. Once taking Poria cocos, this problem may be more serious, making patients weaker, which not only has no therapeutic and health care effects, but also may lead to more serious problems.
Second, diabetics are not suitable for taking diabetics and poria cocos. It should be a terrible thing to have diabetes, because once you have this disease, many foods can't be used, even if you have a drug with high nutrition and multiple effects like poria cocos, diabetics can't eat it. The specific reason is that Poria cocos contains a relatively high amount of starch, which is also the reason why diabetics are discouraged, because diabetics should limit their intake of sugar, and of course the intake of starch should also be strictly controlled.
Third, people with throat problems are not suitable for taking. For patients with throat problems, they can't eat poria cocos, because it has a function of diuresis and dampness, so please pay attention to the trait of dampness, which may be a fatal defect for patients with throat problems. Patients have problems with their own throats, so they need to drink some boiled water and replenish water often to make their throats less dry. Then once they take Poria cocos, there will be less water in their bodies, which will backfire.
