Plant poisoning.
GRINDELIA CUNEIFOLIA
(Ind. Mie-chowl)
Grows in alkaline soils and its blooming season is from August to September. The plant was used a great deal in cases of itching skin eruption caused by poison oak, and is a cure for such disorders. (American Gum Plant)
RHUS DIVERSILOBA
(Ind. E-yal)
Botanical Serum. This is the poison oak itself, of which the roots, during the dormant period, are cut and properly dried. When taken in the form of tea in a quantity of not more than four ounces, it will render a person immune against any further poisoning. This is a bona fide Indian formula.[1] Blooming season from May to June.
[1]I ask my readers not to try this serum pending further laboratory experiments. I plan to subject myself to exhaustive tests under scientific observation and to publish the results.
