The reason I was so interested in those books was about Dr. Seagraves treating 
and curing of TB.
MY Aunt S----- was in a sanitarium with TB [approx 3 years] and no improvement 
in sight.Also another aunts' daughter,   [my cousin] was  in a different 
Sanitarium with TB.
Somebody who knew about this Dr. Seagrave and his treating of TB was able to 
smuggle the herb he used,Umkaloba [spelling ?] to them,eventually they were 
discharged as cured.
This took place back in the 50s
My Aunt S lived to a ripe old age,with a bit of a wheeze .
My cousin just passed away a few years ago.
The Aunts were sisters.
