This is a very imperfectly proved remedy, and it is only possible to present fragments of it. The mental symptoms have not been brought out, but the remedy has some striking features. You will notice the resemblance of this drug to Mercury, and it is an antidote to mercury. In those lingering mercurial bone pains, where the patient has been salivated; the pains come on at night from the warmth of the bed; the body aches; a chronic, sore, bruised state; soreness of the periosteum where the flesh is thin, over the tibia; joints; soreness of the muscles; drawing and cramping; drawing in the muscles of the back; backache, worse at night; worse from the warmth of the bed. The patient suffers from these symptoms in cold, damp weather, as in Mercury. Tendency to ulceration, hence its usefulness in syphilis; old, chronic, syphilitic ulcers; the patient has been salivated; had Mercury rubbed in; he became saturated with it, but it no longer helps. Ulcers in the throat; on the skin; on mucous membranes anywhere. Spasmodic conditions; drawing in the muscles; this may extend to violent spasms; opisthotonos; sometimes the cervical region is affected and the head is drawn back; jerking and twitching of the muscles.
