The molecular formula of camphor is C?H?O.

Natural camphor pills are aromatic organic compounds extracted from camphor tree branches and leaves. Synthetic mothballs is an organic compound containing naphthalene mothballs are mostly white, pungent odor, and sink in water. Generally contain p-dichlorobenzene, naphthalene.

Camphor balls are divided into natural camphor balls and synthetic camphor balls. Natural mothballs are smooth colorless or white crystals, smell fresh, will float in the water. Used to prevent insects, moths, mildew natural mothballs, also known as odor beads, originally from the camphor tree branches and leaves extracted from the organic compounds with aromatic flavor. It is also used in pharmaceuticals, spices, and medicine as a cardiac drug. Synthetic mothballs is an organic compound containing naphthalene mothballs are mostly white, pungent odor, and sink in water.

Role:

The role of the central nervous system Camphor has the role of excitation of the central nervous system, and for the higher centers is particularly significant, a large number of effects on the cerebral cortex motor areas and brainstem, causing epileptiform convulsions, the general dose of camphor on the respiratory center has no obvious effect, in the case of respiratory depression can be seen in the case of some of the excitement.

It is mainly due to the reflex excitation caused by the stimulation of receptors during subcutaneous injection. For the vasomotor center, the excitatory effect is seen only when its function is extremely low, visceral vasoconstriction and cutaneous vasodilatation, and blood pressure rises.
