Keynotes

Characteristics
Clarke

Curare produces muscular paralysis, probably through its action on the nerve

endings in the muscles, without affecting either the muscle substance or the nerve substance, and

without impairing sensation and consciousness. It is thus in many ways the opposite, in its

action, of Nux vomica, though it is said to have the juice of a Strychnos in its composition. It

causes death by paralysis of the respiratory muscles. Reflex action is diminished or abolished

(opp. Nux), and this is one great indication for its employment in homceopathic practice. A cure

of pseudo-hypertrophic paralysis by the 200th has been recorded. A condition resembling

catalepsy has been induced by it; immobility with fixed gaze on waking. Fetidity characterises

many of the secretions and discharges. Two cases of diabetes in middle-aged men have been

cured by Burkhardt with Cur. 4. It is suited to scrofulous children; producing scrofulous

eruptions on skin, eczema, especially of face and behind ears; also liver-spots, yellow-brown. It

favours the formation of corns. Debility short of paralysis indicates it; debility of the aged, and

nervous debility from loss of fluids. Its relation to hydrophobia and tetanus is probably

antipathic. It causes a sensation as if the brain were full of fluid. Piercing, lancinating pains.

antidote its effects. If the poisoning is due to a punctured wound, rubbing in tobacco or salt will

neutralise it. It is an antidote to: Strychnia and to the poison of rabies. Compatible: After Arn.
