I've been asked a couple of times about the quality and freshness of many of the products that we carry. Most of the time they are questions about the NHV herbal tinctures, ES Clear in particular.
Because we distribute a lot of ES Clear they make new batches every couple of months. The product can be stored for up to two years unopened. This is the time limit that they have tested the herb's storage potency. It could probably go longer, but it has only been tested to 2 years.
These tinctures are packaged in brown glass bottles that are needed to stop the degrading and damaging effects of light on the herbs. When available, all of the herbs are organic and wildcrafted.
Once opened the product needs to be refrigerated and the full potency lasts up to 6 months.
