» Radix Clematidis's Detail   » Radix et Rhizoma Sinopodophylli Hexandri's Detail
Gui Jiu (Radix et Rhizoma Sinopodophylli Hexandri) is the confused species of Wei Ling Xian (Radix Clematidis). The roots and rhizomes of another two species, Clematis hexapetala Pall. and C. manshurica Rupr., which are listed in the C.P., are also used as Wei Ling Xian. Gui Jiu is not Wei Ling Xian; this is par ticularly significant because it is listed in Hong Kong as Schedule I (Toxic/Potent) Chinese Materia Medica. It has caused some poisoning incidents in Hong Kong; therefore, caution should be taken while consuming these herbs.
