Characteristics.
      Fl-ac. acts on the lower tissues of the body much like Silica, which it follows and precedes well.
      It is useful after the abuse of Silica. The modalities of the two are different, Fl-ac. having better from cold applications.
      It acts on the bones, especially the long bones, causing caries and necrosis, and favors the expulsion of the necrosed part.
      Fistulae, rectal, dental, and lachrymal come within its sphere.

      T. F. Allen has recorded an experience (N. A. F. H., 1886, p. 288) showing the applicability of Fl-ac., in whitlow.
      A lady spilled some of the acid on her hand and though treated at once with turpentine a few spots escaped on one hand, and these soon gave her great pain, intensely pulsating.
      The pulsations involved the tip of the thumb especially, though this had not been touched by the acid.
      It was not red like the spots touched by the acid but was sore to touch, and when pressed there was a sensation as of a splinter under the nail and in the cellular tissue.
      This lasted some days.
      The whole hand was swollen and hot, better in cool, open air.
      In a workman whose hand was exposed to the fumes of the acid there was intense throbbing pains especially in the thumb, suppuration occurred later and was very slow to heal.
