Botanical name: 

Camphor in small doses is a stimulant, in large doses a sedative, to the nervous system. I do not regard it as having a very extended use in medicine, though for the purpose named, it may sometimes be employed with advantage. In low forms of disease, with insomnia and restlessness, I have used it alone, and in combination with stimulant doses of Opium or Morphia, and Quinine.

As a topical stimulant, it may be employed with advantage, when the integrity of the part is threatened from enfeebled circulation.
