leaf packs or poultices for: wound healing, chilblains, skin eruptions,
joint pains, any simple swelling or bruise, and even tumours. There are no
explanations of the effect but enthusiastic testimonials of dramatic cures
when other means had failed.He mentions a Dr Blanc who has written a book on
the subject'
