![Schematic representation of herbal drug standardization [38] FACTORS AFFECTING THE QUALITY OF HERBAL MEDICINE Different batches of the same herbal medicine may differ in quality due to a number of factors such as: Inter-or intra-species variation: The variation in constituents is mostly genetically controlled and may be related to the country of origin. Environmental factors: The quality of an herbal ingredient can be affected by environmental factor like climate, altitude and other conditions under which it was cultivated. Time of harvesting: For some herbs the optimum time of harvesting should be specified as it is known that the concentrations of constituents in a plant can vary during the growing cycle or even during the course of a day. Plant part used: Active constituents usually vary between plant parts and it is not uncommon for an herbal ingredient to be adulterated with parts of the plant not normally utilized.](profile/Koto-Te-Nyiwa-Ngbolua/publication/291945523/figure/fig2/AS:391361737052161@1470319317321/Schematic-representation-of-herbal-drug-standardization-38-FACTORS-AFFECTING-THE.png)
