The name Zincum was given by Paracelsus, until which it was know to called Mascarite of Gold.

It was Hahnemann who started using Zincum metallicum as a remedy. The pathogenesis were no different beween the metal and the oxide as per Jahr’s Manual.

Hahnemann says: I have employed, with the best results, the metallic zinc in cases for which the oxyde used to be recommended, especially in nervous affections of the heart, airpassages, and the organs of locomotion, in chronic spasms, and in various kinds of obstinate nervous derangements with tearing or burning pains.

This explains the progression of the condition of workers in Zinc factories, after ten or twelve years’ exposure, suffer from the following symptoms: pains in the back; sensitiveness of the soles of the feet; formication, numbness and coldness of the legs; sensation as of a band around the abdomen; crampy twitching of the muscles. Reflex excitability is increased so that irritation in one part of the body will produce violent jerking in another. Muscular sensibility is lessened, hence patient staggers when his eyes are closed, or when he is in the dark. There are muscular tremors which almost simulate those of shaking palsy. Still later, the gait becomes stiff, motions are spasmodic with the step on the full sole. From involvement of the sympathetic nervous system there are anaemia and progressive and general emaciation.

Farrington says that Zinc is an invaluable drug when the patient is nervously too weak to develop a disease, and hence he suffers all the consequences of hidden disease, or disease spending its force on the internal organs. To give you an illustration of this in exanthematous diseases, we find Zinc called for in scarlatina, or in
measles when the eruption remains undeveloped.

The pain in the ovaries, are relieved when the menstual flow starts.
The asthma is relieved as soon as the patient expectorates.

Zincum is indicated in several forms of headache. One of them is a stinging, tearing headache, worse in the side of the head, greatly increased by wine; this headache is also worse after dinner. Zinc is indicated in obstinate pain in the head, obstinate in its persistence, yet intermittent in its quality, now very severe, and
now fading away, but continually returning.

Zincum is the drug in enlargement of the liver.

The cough of Zinc is spasmodic, as if it would draw the chest in pieces. The sputum may be bloody. This is particularly noticed just before or during a menstrual period. It is also aggravated by eating sweet things. You will sometimes find Zincum helping in children, who, every time they cough, put their hands on the genital organs.

In its action on the male genital organs Zincum is similar to Conium. It is indicated in spermatorrhoea following long-lasting abuse of the genital organs, with great hypochondriasis. The face is pale and sunken, with blue rings around the eyes.

Clarke mentions that Zincum is noteworthy in states of nervous exhaustion, which usually crave stimulants. There is the aversion to wine. Other characteristic aversions are: Meat (especially veal); sweets; cooked or warm food. Eating as well as wine-drinking
