Honokiol, a plant lignan isolated from the bark and/or seed cones of the Magnolia tree. The Chinese call it “hou po”, and use it to treat digestive disorders. The Japanese refer to it as “saiboku-to”, and sure enough they drink it as a tea to treat anxiety. It has been around as part of traditional medicinal practices for about 2, 000 years, but it burst on the CLL scene just a few days ago when the research group from Dana Farber/Harvard Medical School published a cell line study in the latest issue of “Blood”.
