Hi Charlie,
I think the book you are writing will help fill a gap in the market. I have an intense interest in herbalism and have many good books which are great for beginners yet i find it difficult to advance from that - apart from doing a degree in the subject!
I wish to blend herbs but find it hard to find EFFECTIVE and SAFE guidance on doing this to perform greater benefit to illness.
In the past i have experimented and used too much or too little to be of any use. A book with enough detail , yet does not require a doctorates degree to understand would be very useful!
Keep us posted how things are progressing - any rough ETA of the book at the moment?
