Aqueous Solution (35 per cent) of Formaldehyde Gas (FORMALIN)
Is a powerful disinfectant and deodorant; a potent poison. Prevents growth and kills almost any pathogenic micro-organism. It seems to have the peculiar property of eating into malignant tumors, leaving the surrounding healthy tissue uncharred and unchanged. A plug of cotton wool soaked in a 20 per cent solution of Formaldehyde, and applied for a few hours, will produce a necrotic slough, which must be scraped away before the next application, otherwise it hardens.
Formalin in hot water as vapor most valuable therapeutic agent in pertussis, phthisis, in catarrhal affections of upper air-passages.
