The use of herbal remedies had increased significantly in the last one decade in Nigeria. This has led to the production of herbal products with bogus claims. The microbial quality and antibacterial properties of two Nigerian herbal remedies with such claimed efficacy of curing all manners of microbial diseases were assessed. The herbal remedies were discovered to be contaminated with the following microorganisms:
Bacillus subtilis
,
Bacillus coagulans
,
Bacillus cereus
,
Basidiobotrytis sp,
Oedocephalum sp,
Varicosporium sp and
Articulospora inflata
. Antibacterial analysis using the killing rate revealed that the herbal remedies had bacteriostatic and not bacteriocidal effect. Qualitative phytochemical screening of the herbal remedies revealed the presence of saponin, tannins, alkaloids, anthraquinone and cardiac glycosides which suggest possible antimicrobial effect. However, the presence of microbial contaminants in the herbal remedies suggests that they may serve as source of infection to end users.
