Magnolia bark (hou po)

Magnolia officinalis

Traditionally attributed effects: makes qi descend, dries dampness and resolves food stagnation and phlegm.

Safety notes

Not during pregnancy or with stomach or spleen deficiency. Traditional use is no proof of effectiveness; if you are pregnant, breastfeeding, taking medication or have a medical condition, consult a doctor or pharmacist.

Preparation

Bark. Usually as a decoction, together with other herbs.

Use in traditions

Described in the classical Chinese materia medica, in the group 'aromatic herbs that transform dampness'. Hou po makes the qi descend in a bloated abdomen, constipation and tightness in the chest; it is part of Ban Xia Hou Po Tang (Japanese: Hangekobokuto) for a 'lump in the throat' due to tension. The bark contains magnolol and honokiol.
