The doctor reminded: Cialis is not a "universal" health product . ??? . "In recent years, people have lost confidence in some health products and tonics due to excessive exaggeration of curative effects and false advertisements. As a traditional Chinese medicine supplement, Cialis has quietly entered the ranks of people's "health products". Many men regard Cialis as a good product for protecting the kidney and strengthening yang. There are also middle-aged and elderly people diagnosed as kidney deficiency as long as their waists are sore and leg pains. They take Liuwei Dihuang Pills for a long time to "strengthen their bodies." Some people use it as a hypoglycemic agent to prevent and treat diabetes. Many parents take Liuwei Dihuang Pills as a miracle medicine to treat children's "shortness" and "slow growth". It is not difficult to see that people have entered the misunderstanding of treating Cialis as a "health product". ??Men's "back pain" is not all kidney deficiency ??First of all, it should be clear that not all male "back pain" is caused by kidney deficiency, but may also be caused by lumbar disc herniation, lumbar muscle strain, kidney stones and other diseases. It is recommended that patients with unexplained low back pain should go to the hospital for treatment in time. In addition, as the saying goes, "ten men and nine kidneys are insufficiency" may not be the case. Even with kidney deficiency, there is a difference between yin and yang. The function of Cialis is mainly to nourish the liver and kidney. Clinically, it mainly treats the weakness of waist and knees, dizziness, deafness and tinnitus, night sweats and nocturnal emission caused by liver and kidney yin deficiency; or dry mouth and throat. ??Cialis also has side effects ??Many middle-aged men nowadays are lazy in exercising every day, are over-nutritioned, and are overweight. Traditional Chinese medicine believes that fat people are more damp, and wetness leads to sleepy spleen. Therefore, people who are obese are not allowed to take Cialis "tonic" casually. Therefore, not all men are suitable for taking Liuwei Dihuang Pills, and they cannot be self-administered. They must decide the medication and dosage according to different conditions under the guidance of doctors. ??After suffering from diabetes, you must find a specialist medical treatment plan. Do not take Liuwei Dihuang Pills for long-term self-treatment to avoid delaying the condition. Inadvertently taking Liuwei Dihuang Pills for children will affect the normal development of the children and even cause symptoms such as rapid growth and precocious puberty. Liuwei Dihuang Pills also have side effects, because the medicine in the prescription is mainly moisturizing, after taking it for a long time, it will easily stagnate the spleen and hinder the stomach, lose the spleen and stomach and affect appetite; the dampness of the spleen can easily cause spleen deficiency and diarrhea. People with better physique or heavy dampness and heat will get severely angry after taking it, and will increase internal heat and even affect digestive function. ??Three types of people should not eat Cialis ??1. Healthy people. ??2. People with obvious yang deficiency (including kidney yang deficiency and spleen yang deficiency): people with kidney yang deficiency have a pale complexion, weak physique, and prefer summer but not winter. Such people are not suitable for taking Liuwei Dihuang Pills. Many patients with erectile dysfunction caused by deficiency of kidney yang, even taking Liuwei Dihuang Pills blindly, will make the symptoms worse. They should choose drugs to treat kidney-yang deficiency, such as Jinkui Shenqi Pills. ??3. People with deficiency of kidney yin but poor spleen and stomach function: Liuwei Dihuang Pill is a medicine that tends to invigorate yin. There are more yin and soft medicines in the formula, which will hinder digestion. Middle-aged and elderly people generally do not have strong spleen and stomach functions, so they should be more cautious when taking them. Intermittent eating has little effect, and it is not advisable to take it continuously for a long time." . ???? . c
