The efficacy and function of camphor oil

Camphor oil is an oily liquid that is mainly used externally. It is widely used in life and clinically, and its effects and functions on the human body are also magical. Of course, when using camphor oil, you should also pay attention to usage, dosage and some taboos. At the same time, using large amounts of camphor oil is likely to cause adverse reactions to the stomach, so be careful about the dosage.

1. Effects on the central nervous system:

Camphor can excite the central nervous system, enhance respiration and circulation, and its excitatory effect is particularly evident when the central nervous system is in an inhibited state. The main reason is the reflex excitement caused by stimulating the receptors at the time of subcutaneous injection.

2. Effect on the circulatory system:

In the isolated heart, the excitatory effect is only seen when it causes failure. For the vasomotor center, the excitatory effect is only seen when its function is extremely low, the visceral blood vessels contract and the skin blood vessels dilate, and the blood pressure rises. It has no effect on normal myocardium, but high concentrations can inhibit it. Therefore, some people believe that it is effective for patients with circulatory collapse or acute heart failure; but some people are skeptical or negative about its efficacy.

3. Effects on gastric mucosa:

Taking camphor can make the stomach feel warm and comfortable. Large amounts can cause nausea and vomiting.

4. Local effect:

Camphor has a mild irritating and antiseptic effect when applied to the skin. If you apply it vigorously, it will cause redness, while if you apply it lightly, it will feel like mint and have a cooling sensation. It is caused by stimulation of cold receptors. It also has analgesic, antipruritic and mild local anesthetic effects.

5. In vivo process:

Camphor is easily absorbed through the mucous membranes, subcutaneous tissue, and muscles. It is also quickly absorbed orally and detoxified quite quickly in the liver, where it is oxidized into camphor alcohol and then combined with glucuronic acid to be excreted in the urine. Note that large doses can cause epileptic convulsions. Symptoms of poisoning include headache, loss of consciousness, trembling, and ultimately death due to exhaustion.
