Factors Affecting Shelf Life

The shelf life of Ayurvedic medicines depends on several factors, including.

1. Quality of raw materials
2. Processing methods
3. Packaging and storage conditions
4. Presence of preservatives
5. Chemical composition and stability of the ingredients

Proper storage is crucial in maintaining the potency and safety of Ayurvedic medicines. Most Ayurvedic medication should be stored in a cool, dry place, away from direct sunlight and moisture. Some preparations, such as medicated oils and ghee, may require refrigeration to extend their shelf life.

Expiration Dates and Safety

While many Ayurvedic medicines have a long shelf life, it is essential to be aware of the expiration dates and discard any medicine that has passed its recommended usage period. Using expired medication may lead to reduced efficacy and potential safety concerns.

It is also important to note that some Ayurvedic medicines, particularly those containing metallic preparations, should only be consumed under the guidance of a qualified Ayurvedic practitioner. Improper use or consumption of these medicines may result in adverse effects.
