Source & Nature
Streptomycinum is the homeopathically potentized form of streptomycin, an aminoglycoside antibiotic and natural product of the soil actinobacterium Streptomyces griseus. The free base is C21H39N7O12 (MW approx. 581.6 g/mol, CAS 57-92-1, PubChem CID 19649); the mother substance is usually the sulphate salt. Streptomycin was isolated in 1943 by Albert Schatz in Selman Waksman's laboratory at Rutgers University and was the first antibiotic effective against tuberculosis, for which Waksman received the 1952 Nobel Prize.
Preparation
Prepared by serial dilution and succussion from streptomycin (commonly streptomycin sulphate). Remedia lists decimal (D9-D30), centesimal (C9-C200), Korsakovian (1MK-100MK) and LM (LM3-LM30) potencies as saccharose globules or ethanol-water liquid dilutions; Indian pharmacies (Lords) supply potencies such as 6CH, 30CH and 200CH.
