Ruta is another remedy often overlooked. It is sometimes overlooked and Rhus or Argentum nitricum given, or other remedies not fully related to the case are given because Ruta is not well known. Many of its symptoms are difficult to classify in the Repertory. A knowledge of its nature must be obtained. It falls under a class of complaints that resemble Rhus, in that it is sensitive to cold, aggravated from cold, damp weather; aggravated from becoming cold, and the complaints are often brought on from straining the part; overstraining or overexertion of parts, but principally confined to parts that are of a tendinous character aponeurotic fibres; white fibrous tissue; the flexor tendons especially flexor tendons that are overstrained by exertion. Rhus has something like this, but nothing like what is found in Ruta. Ruta often suits in various surgical conditions; periosteal troubles from injury. Periosteal trouble where the flesh is thin over the bone; over the tibia. Bruises go away slowly and leave a hardened spot; thickening of periosteum; a knotty, nodular condition; it remains sore; slow repair. A lump in the periosteum that has existed for months or years; sensitive and sore and nodular; as a result of a blow with a stick or a hammer, or from bumping the shin bone, Bruises: In farmers, woodmen, mechanics, from holding a hammer or iron instrument; hard nodules form in the palm from clasping the hand over an iron instrument in projecting it forward, as from using a crowbar; a hardened mass of tissue in the tendons, like a bursa. Tendency to the formation of deposits in the periosteum, in bone, in tendons, about joints. The especial location is in the wrist; bursae and nodules form in this part. Overstraining of tendons and in the place where it is likely to give out a nodule will form in the tendon; lumps, bunches, little tumors in the tendon. Gradually increasing contraction of flexors, so that the hands become permanently flexed; the foot becomes flexed so that the sole becomes increasingly concave, and the toes are drawn under from overstraining and violence to the flexors.
