Also, after an operation, I used Yarrow before I entered hospital and then put drops under my tongue straight afterwards. It started to remove the anaesthetic from my system in fact it was coming out my pores and my nightie was wet with it. I asked my husband to take me home before somebody noticed and thought it was infection. Once home, I just changed nighties often until it all settled down. I pick it in the garden these days.
One big handful, in a saucepan with a pint of water gently heat about half an hour. Then I leave it to cool in that water before straining. With this method I put a tablespoonful in every drink until the flu has gone. I always have some in the freezer and out it comes at the first sign of sore throat or sniffle.
