Herbal medicines - herbal origin; pharmaceutical products - synthetic origin.

The influx of herbal Medicine has been increasing in the mainstream of healthcare, ranging from its wide consumption and acceptance in Nigeria. It also has huge risks that require high regulatory checks. The National Agency For Food and Drug Administration and Control (NAFDAC) outlined the Manufacturing Guidelines for Herbal Medicinal Products to guarantee that the manufactured products are in conformance with quality standards. These guidelines are to ensure that no Herbal Medicinal Products are distributed, advertised, exported or manufactured unless it is registered in conformance with the provisions of the Food, Drugs and Related Products Act Cap F33 LFN 2004 (formerly decree 19 of 1993).

Although, development and research activities of finished Herbal Medicinal Products are not subjected to these guidelines. The production of Herbal Medicinal Products of sterile source — implants, injectable, solution, ophthalmic, infusion — are not part of this guideline. Monitoring is one of the key factors in the production of herbal medicinal products to ensure its quality standard. Herbal Medicines are manufactured from herbs, precisely herbal origin, which is quite opposite to the synthetic feature of pharmaceutical products. This makes Herbal Medicines subjected to various conditions.
