Documented Uses

• Magnolol and honokiol, biphenyl compounds, were isolated as anti-emetic principles from the methanolic extract of Magnolia obovata bark.
• Magnolia bark extract (MBE) is an extract of the dried stem, root, or branch bark of magnolia trees that has been used historically in traditional Chinese and Japanese medicines, and more recently as a component of dietary supplements and cosmetic products. /Magnolia bark extract/
• Magnolia officinalis is a commonly used traditional Chinese medicine for treating gastrointestinal disorders.
• Saiboku-To, a mixture of ten different herbal extracts, has been used in Japan and Czechoslovakia for corticosteroid-dependent severe asthma to reduce the maintenance doses of corticosteroid. Magnolol has been considered to be an active component of Saiboku-To.
