Camphor Essential Oil
Camphor is extremely pungent. Diffuse with care.
Camphor is considered by many aromatherapists to be too strong to be used effectively, especially as a single oil. A small amount of camphor taken internally could easily prove fatal. Overdose, even topically, has been known to cause convulsions and vomiting. Pregnant women and people with epilepsy or other seizure disorders should certainly avoid its use altogether.
