      Common name. Glacial Phosphoric Acid. Preparation. One part of the purified Glacial Phosphoric Acid is dissolved in ninety parts of distilled water, and then ten parts of Alcohol are added tom make the 2x dilution.

The chief sphere of action of Phosphoric Acid is upon the nervous system, in which, from waste of nerve tissue or from depression, it produces debility without erethism (with erethism, Cinchona), giving rise to conditions simulating those which result from continue grief, over-exertion of mind or body, sexual excess, etc. Through this influence its chief local effects are upon the kidneys and male sexual organs, and next upon the bones and skin, as indicated by its pathogenesis.

Phosphoric acid represents a mental and physical weakness and torpidity of nature found in no other drug. It is especially useful in neurasthenia, or debility. This may have resulted din young people, in whom the drug is most often useful, from growing too rapidly, the physical system developing at the expense of the nervous and mental, or it may result as a remote effect from depressing emotional causes, such as grief, sorrow, homesickness or disappointed love, but more often the neurasthenia is of sexual origin, and results from long continued sexual excesses or onanism. The patient has involuntary emissions during sleep, or after urinating or straining at stool. Is greatly exhausted therefrom, and has vertigo, weakness of the back and limbs, mental torpidity, brain fag, etc. The sexual powers are so weakened that erections are deficient; during an embrace emissions take place soon, and after coition the patient is greatly exhausted, with symptoms as above stated, and burning in the spine. It is unquestionably the chief remedy in spermatorrhoea and sexual neurasthenia. It has also been used for swollen and tender testicles. Herpes preputialis with tingling. Sycotic excrescences. Fig warts complicated with chancre. In women it has been useful for menorrhagia of dark blood, with great weakness; debility from long-continued nursing; leucorrhoea; meteoristic distension of the uterus. In all nervous diseases the urine is loaded with phosphates, and there is generally aching in the small of the back. Frequently the hair turn gray early, and falls out after the emotional causes above named. The drug causes polyuria, and is the chief remedy in diabetes insipidus, and is unquestionably curative in diabetes mellitus, as the experience of the author and many others abundantly testify. Catarrh of the bladder. The drug may be useful in chorea and hysteria, with characteristic weakness and mental symptoms. The peculiar mental apathy of Phosphorus ac. with its prostration, involuntary stools, nosebleed, etc., has led to its frequent use in typhoid and other low forms of fever. A clinical symptom is a red streak in the center of the tongue, which widens in front, the urine often looks milky, contains albumen, and decomposes rapidly, and the abdomen is tympanitic. It does not reach the very profound low types of fever, such as call for Arsenicum or Lachesis or even Rhus tox. Has often proved useful in intermittent fever, probably not of malarial origin. Acid dyspepsia (see stomach symptoms). Chronic diarrhoea, painless, not debilitating. Painless diarrhoea during cholera time (Phosphorus). Sometimes useful in laryngitis, tracheitis and bronchitis; cough arising from tickling low down in the chest, worse in the evening after lying down; expectoration, mostly in the morning, tasting salty. Capillary bronchitis (see symptoms.). Phthisis, with great weakness in chest (Stannum). Nervous palpitation of the heart, from causes previously named. Spinal anaemia from sexual excess or onanism. Has proved palliative in caries of the lumbar vertebrae. Swelling and sponginess of bones. Caries (not necrosis.). Periostitis. Hip-joint diseases. Painless swelling of glands. Warts indented or pedunculated. Condylomata, with bone pains, complicated with chancre. Atonic ulcers on legs. Skin adhering after ulceration grows to the bone. Acne of young people from onanism. Blood boils. Chilblains.
