Hi Esther, A nice medicine chest! The herbs (apart from the tea tree oil which is indeed a help) are all quite nourishing and you are right, they have those subtle extra qualities also. I am planning on adding more Yarrow / Duizendblad to mine this year. I like to keep some fresh first aid plants around the place and I am sure you have some around too. I cut my finger, whilst fixing something on my roof yesterday and a quick pluck of 1/2 a fresh yarrow leaf stopped the bleeding almost instantly. It reminded me to get some downstairs in the house but fresh is best and it likes the sunshine so I am thinking of which way to preserve it this time.
