    I would love to join you on one of your foraging course. Apparently, the listed course are fully booked. I wonder if you are planning to organise more foraging course in the future. If you do, would you be able to inform me about it, please.

      We add new courses throughout the year so the best thing to do is keep your eye out for new ones. If you enquire at [email protected] you will be able to find out if we are putting up any courses near you.

    Hi is it ok to eat raw water mint, I picked some that was growing in the silt near a river?

    1. Eric Biggane says:

      It’s best to avoid eating raw leaves from plants that are in water due to liver fluke but if the leaves were, and had been out of the water, you should be fine. Liver fluke require sheep as part of their life cycle, so if there are sheep anywhere along a water course, there could be liver fluke. Cooking destroys the parasites.
