Send me your email id. I will send you (book) link that provides answers to your questions on TLC
You can send an email to [email protected], for me to send you the pdf link from where you can download the book.
Also try becoming a member of HPTLC Association (google for this). It is easy. They have TLC mongraphs for over 60 medicinal herbs which you can download if you become a member. The chief of this association is Anne Schibli of CAMAG. Quite a useful site.
