What is teasel root? What is it used for? Also known as
dipsacus, teasel is a flowering plant similar in appearance to a
lilac, with long, cylindrical flowers and bracts (leaflike
protuberances) that are curved and thorny. The plant, which
grows throughout Europe and parts of Asia, can reach a height of
five feet, and bears small fruits that resemble nuts. Teasel
roots are used medicinally. The roots are dug up in the summer
(usually July and August) and cleaned, with the fibrous material
and dirt removed. The roots are then cut into slices and dried
in the sun before being used in herbal preparations. In
traditional Chinese medicine, teasel root is affiliated with the
Liver and Kidney meridians, and has bitter, pungent and warm
properties. Its functions are to tonify the liver and kidneys,
promote blood circulation, and strengthen the bones and tendons.
Teasel root can be used internally or externally. Internally,
teasel root treats pain and weakness in the knees and lower
back, helps repair damaged tissues
