Compound camphor powder

Compound camphor powder is a relatively common plant in our lives. Maybe you don’t use it often, and some people have never heard of this medicine. Everyone knows what camphor is, right? In fact, camphor is extracted from camphor trees. The older the camphor tree, the more camphor it contains. The camphor we usually see is the one placed in the cabinet. In fact, the effect of camphor is not that small.

Compound camphor powder has a local paralyzing effect and can be used to treat skin allergies or skin diseases such as eczema. It is beneficial for these skin diseases because the compound camphor powder has analgesic and antipruritic effects.

Pharmacological Action

1. Local effects: Camphor has a mild irritating and antiseptic effect when applied to the skin. If you apply it vigorously, it will have a reddening effect; if you apply it lightly, it will feel like mint and have a cooling sensation, which is due to the stimulation of the cold receptors. It also has a mild local anesthetic effect. Camphor has a stimulating effect on the gastrointestinal mucosa, making the stomach feel warm and comfortable, while large amounts can cause nausea and vomiting. Camphor ointment is used clinically to relieve pain and relieve itching. Oral administration has a carminative and mild expectorant effect.

2. Effect on the central nervous system: The systemic effect of camphor is mainly to excite the central nervous system, especially the higher centers. It acts in large quantities on the motor area of ​​the cerebral cortex and the brainstem, causing epileptic convulsions. Camphor at normal doses has no significant effect on respiration. Under extremely depressed conditions, some respiratory excitement may be seen, mainly due to reflex excitement caused by stimulation of the receptors during subcutaneous injection.

3. Effect on the circulatory system: Camphor preparations were once widely used as cardiotonic drugs, but the results reported by various researchers are very inconsistent and there is no definitive conclusion yet. It has no digitalis or adrenaline-like effects. It has no effect on normal myocardium, but high concentrations can inhibit it. In isolated hearts, the excitatory effect is only seen when failure is caused. The excitatory effect on vascular motility is only seen when its function is extremely low, causing visceral blood vessels to contract and skin blood vessels to dilate, leading to an increase in blood pressure. Therefore, it is believed to be effective for patients with circulatory collapse or acute heart failure; however, some people are skeptical or negative about its efficacy. Some people have reported that a water-soluble metabolite of camphor in animals, oxidized camphor, has obvious cardiotonic, blood pressure-raising and respiratory stimulating effects. Its trade name is Vitaeamphor. Use with caution in pregnant women.
