Try to avoid applying wheatgrass too frequently, or taking too much of it because this can sometimes slow the healing process. You only need to apply or take a small amount.

For injuries, skin conditions etc. apply a little wheatgrass extract just once every second day. 

To help you improve and maintain good health, take a teaspoonful of wheatgrass extract (Supershots is our Company’s brand of wheatgrass oral extract) – on alternate days only – and persevere. Hold the liquid in your mouth for a minute before swallowing. This allows time for the bioactives in the extract to make their way into the bloodstream where they do their work to help you achieve and maintain better health.
