Borneol for external use on skin

Borneol appears very frequently in people's lives and is very useful to people. For example, it has the effects of clearing away heat and fire, relieving pain, as well as antiseptic, refreshing the mind, resisting fatigue, etc. Borneol can be applied externally on the skin or taken orally by the human body. There are many contraindications when applying borneol externally on the skin. The following is a detailed introduction to the contraindications of applying borneol externally on the skin.

First, people who are not suitable for taking borneol

Because borneol is cold in nature, pregnant women and patients with qi and blood deficiency should not take borneol. It is also not suitable to take it in excess, otherwise it may cause side effects to the body. The Chinese medicine classic "Bencao Jingshu" believes that although borneol can treat stroke after taking it, if the cause of this disease is not due to the invasion of external wind evil, but due to deficiency of qi and blood, then taking borneol will not be able to cure the disease. In addition, if a child is frightened after vomiting or diarrhea, he or she should not take borneol, otherwise the disease may worsen.

Second, do not overdose.

When using this medicinal material, you must pay attention to the dosage, because borneol is cold in nature and is not suitable for large doses. Generally speaking, we have many ways to use this kind of medicinal material, but it cannot be decocted in water. Instead, it should be ground into powder and made into pills or powder for oral administration. It can also be soaked in white wine and taken orally. In addition, external application of the powder is also a good way to use it.

Third, do not take it if you are allergic to it.

Modern scientific research has found that borneol itself contains certain toxins, so if scientific methods are not used, it is easy to cause poisoning or allergic reactions. If borneol is used in large doses, it will irritate the gastrointestinal tract, causing nausea, vomiting, abdominal pain and diarrhea, and serious problems will occur in the liver and spleen. The central nervous system will also be overexcited, eventually leading to convulsions, loss of consciousness, and cramps. If the problem is more serious, it may even lead to respiratory failure and death. If an allergic reaction occurs after taking borneol, the specific symptoms include rashes all over the body, itching of the scrotum or lips, and discomfort such as shortness of breath, palpitations, and chest tightness. Clinical trials have also found that if borneol is used to treat hemorrhoids, a small number of people will experience itching and burning around the anus and red papules on the skin. At this time, stopping the medication or taking anti-allergic treatment can restore the condition.
