Dandelion Side Effects and Contraindications

As a traditional Chinese medicinal material that can be used as both food and medicine, the effect of dandelion flower is of course very good. However, we all know a truth: All medicines are poisonous. Pharmacological studies have shown that dandelion flowers also have some side effects and taboos if taken improperly.

The key side effects of dandelion flowers are as follows:

1. After taking too much of the basic dosage, there may be some digestive tract reactions, such as nausea, vomiting, abdominal discomfort and mild diarrhea. The research shows that after oral administration of a large dose (30g/kg) of the decoction for 3 days, it can be seen that the liver and renal tubular squamous cells of the experimental rabbits were slightly swollen, the renal tubules were smaller, and there were no other significant changes. In subacute toxicity experiments in mice and rabbits, a small amount of tubular and turbid swelling of renal tubular squamous epithelial cells may appear in the urine.

2. The main reason for the inappropriate use of medicine is that heat and cold cannot be distinguished, and dandelion is used indiscriminately to treat various infections without a good analysis and dialectical analysis. Most of the infections heard in clinical medicine are fever syndromes, and the use of dandelion flowers is generally not likely to have side effects. However, a very small number of infections are yin syndromes with no fever symptoms. The current medical history is mostly long, and the patient has a weak and cold constitution. The editor has seen many people use large doses of dandelion to treat Yinyi syndrome, and as a result, the patients experienced poor appetite, laziness, fatigue, sweating, and pale complexion. The infection showed no signs of improvement. Indiscriminate use of dandelion flowers, which have the effect of clearing away heat and removing internal heat, simply regards them as having the ability to inhibit bacteria and reduce inflammation, which will cause side effects.

3. Allergic symptoms After taking Chinese medicinal materials made from dandelion flowers or medicinal wine soaked with dandelion flowers, some people will experience symptoms such as hives or itching all over the body. This is a skin allergy to dandelion flowers. Sometimes, many people also experience symptoms such as coldness, pale face, and dark blue mouth after using dandelion flower injection, which is also a skin allergy.
