Physiological Action

This agent when applied locally is an irritant, and causes itching and vesicular eruption of the skin. This may extend to the mucous surfaces and cause redness and tumefaction of these surfaces. When taken internally there are colicky pains in the abdomen which are worse at night. These are accompanied by diarrhoea with tenesmus, and bloody stools and urine, and fever, which is often typhoid or intermittent in character. There are pains of a rheumatoid type in the joints and lumber region, which are intensified by rest and heat. The fibrous tissue is the seat of the most of its action.


This remedy is indicated in those of a RHEUMATIC DIATHESIS who suffer from the effects of having been wet while overheated. There is great restlessness, anxiety and apprehension. The patient cannot remain in a quiet position, must change to obtain relief from the pains which are as if the parts had been sprained or as if the muscle or tendon had been torn from its attachment. The ailments are apt to be the result of spraining a muscles or part, overlifting or from lying upon the damp ground. The symptoms are worse after midnight, during wet weather, and while at rest.

It is of service in TYPHOID FEVERS when the delirium is of a mild type. He desires to escape. There is great restlessness with a momentary relief from motion. The tongue is brown, dry, cracked or red, with a triangular, red tip. The abdomen is tympanic, and the diarrhoea is involuntary, brown and cadaverous. There is a frontal headache, with pains in the limbs. In intermittent fever it is of service when in connection with the general symptoms there is a dry, teasing cough during the chill, and hydroa upon the lips.

It is useful in LUMBAGO when the pain is worse on attempting to rise. There are rheumatic pains in the back and stiff neck from sitting in a draft. There is relief from action.

It should be remembered in VESICULAR ERYSIPELAS when the skin looks dark red, and is covered with vesicles; and in skin diseases where there is a vesicular eruption with oedema, burning and itching, and in which any cool draft aggravates the condition.

It is beneficial in SCARLET FEVER when the child is drowsy and restless. The tongue is smooth and red. The fauces are oedematous and the glands are enlarged. The eruption is military in character and does not develop properly; also in CELLULAR INFLAMMATION where there is the formation of pus, and severe pains. The parts are dark red, and there is extreme prostration.

It is indicated in CONJUNCTIVITIS and IRITIS of traumatic or service in SCROFULOUS OPHTHALMIA and ORBITAL CELLULITIS, when there are oedematous swelling and acrid discharges. It often affords relief in parotitis, and in CARDIAC HYPERTROPHY, the result of over – exertion, when there is a sense of numbness of the left arm.
