Quality Control of Herbal Medicines- The Need of Time
Quality is of prime concern to human beings in all aspects of
life. Due to the stringency in the
regulations, the quality of the synthetically manufactured pharmaceuticals is
maintained up to the mark which assures both safety and efficacy of the
pharmaceutical products.
Herbal
preparations are made from one or more herbs. If more than one herb is
used, the term mixed herbal product is
used. Finished herbal products and mixed herbal products may contain excipients in addition to
the active ingredients. In some countries, herbal medicines may contain, by tradition, natural organic or inorganic
active ingredients that are not of plant origin Most herbal product labels cannot fully reveal the contents of a
container. Study reveals less
than 50% chances of actually achieve the label claim.
Quality control and standardization of herbal products
depends on various factors like age/ part of plant collected, temperature,
sunlight, time of collection, drying process, storage etc., which ultimately
affecting the quality and therapeutic value of product.
Need for quality control
of herbal medicines
} Herbal remedies are
being used throughout developed
and developing countries and represents a substantial proportion of the global
drug market and show high demand internationally.
} Lack of technical documentation and Lack of specific process for manufacturing of
their formulations
} Lack of approaches in development of modernized dosage
forms.
} Lack of Routine quality control methods for finished
preparation and are required to establish
internationally recognized guidelines for assessing their quality.
} Several reports on
incident of toxicity and adverse
effects link to plants and their formulations are available alongwith
the toxicity of trace metals on
human health and environments.
The process where the qualitative and quantitative values of herbs are
measured against the prescribed or set standards and parameters is known as
standardization and is done for the raw material, process and of the finished
products.
