I am using Echinaforce^® for colds and flu. My question is this: as the product is natural and organic, how well does it hold its effectiveness until the expiry date even when the bottle has been opened.

Yes - the active ingredients in Echinaforce^® are stable to its use-by date even if a bottle has been opened.

The product is a licensed medicine and being so, we have to do many tests in order to determine how stable it is.

These include storing the product under a higher temperature as well as what is known as ‘in-use’ stability – this is when we simulate in the laboratory, usage of the product each day as it would be used at home.

These tests make us certain that the quality of the product is retained when used in the real world.
