Analgesic, anticonvulsive, expectorant, sedative, antitumor
This herb is used for cold, stubborn phlegm with a full distended
feeling in the chest and difficult expectoration. It is also used
for wind conditions that cause convulsions, paralysis, spasms, stroke,
dizziness, or epilepsy.
Chinese herbalists claim to have used it with success in some kinds
of cancers and externally for suppurating sores and abscesses. When
used externally, the unprepared root is indicated; otherwise it
is used in its prepared form or with fresh ginger to counteract
its toxic properties.
