Yoga book with asanas index by afflictions

[Meg]

Do you know a book on yoga where I can find asanas grouped by the suitability for the specific body part condition/ illness/ affliction?
E.g. when I'd like to find poses beneficial for thyroid, digestion, neck pain, e.t.c.

Hi there. I highly recommend Yoga as Medicine by Dr. Timothy McCall, one of the pioneers in the field.
