The Gumweed person is weak, neurasthenic, frequently ill or suffering frequent relapses, may have chronic fatigue syndrome, [and] turns to invalidity as a refuge. Those Gumweed types who have Chronic Fatigue Syndrome characteristically drive themselves so hard that disabling illness is indeed their only refuge. The quality of Gumweed is the understanding of illness as a gift, the ability to learn the lesson & move on, whether to health & strength, or if the disease is a continuing karmic necessity, to transform through illness.” Cautions:

Toxic in high doses.

Pregnancy.
