Lac caninum
Dog's milk · Bitch’s milk, Dog's milk · Sarcode
Those who benefit most from Lac can. tend to lack self-confidence or feel self-contempt. Often restless and nervous, they may be highly sensitive to sensory stimulation. An active imagination and excitable nature combine to engender irrational fears that may develop into phobias. They may be prone to bouts of depression.
A typical symptom in those who respond to Lac can. is a feeling of “otherworldliness,” as if the self is floating just above or behind the body, or a sensation that is often described as “floating on air.”
Lac can. is used for irrational phobias and for acute sensory hypersensitivity. The remedy is also considered particularly effective for the throat, the nervous system, and the female reproductive system. In all conditions, symptoms tend to move from site to site around the afflicted area of the body.

History
A beginning in this remedy was made by Dr Nisip and after Reisig it was used by Bayard.
After Bayard's death Dr. Dyer gave me a vial of the 30 th potency, made by Reisig, from which the potencies have mostly been made.
All the milks should be potentized, they are our most excellent remedies, they are animal products and foods of early animal life and therefore correspond to the beginning of our innermost physical nature.
If we had full provings of monkey's, cow's, mate's and human milk they would be of great value. Lacdefloratumhas done excellent work, and so has this remedy. Lac caninum is in its beginnings yet, although it has made some marvelous cures, but many of its symptoms axe doubtful and it would take a century to confirm them.

Hering adds that the remedy was revived by Reisig, of New York, who used it successfully in the treatment of diphtheria. After Reisig the remedy was used by Bayard and Swan, to whose indefatigable exertions we owe the present status of this medicine. Swan's potencies were prepared from Reisig's 17th. The …
