Yes, natural is preferable to chemicals. Although I don't recognise all of @mudcat36's plants, in South Africa we have the willow and perhaps tansy ... I will confer with our local experts about the others. I use basil and mint a lot, especially for coughs and colds, and of course garlic which is a natural antibiotic. Also cannabis leaves, infused with a bit of coconut oil, which helps insomnia ... add a bit of honey. As I am very close to the beach, there are amazing succulents on the dunes known as Natal sour fig, which are great for stings, eczema etc. and apparently a whole lot of other ailments which I'll research and post. I'll also go down to the beach to photograph them to show my fellow steemians. Great topic, excellent choice @danielsaori.
