Anthraquinones are widely distributed in the plant
world and are responsible for the brillant reds and
oranges in some plants. It was also at one time much
researched as a cure or prevention for malaria. Due to
its bad taste, the English deveoped gin to get it down
better.
One story is that of a careless chemist who got the
formula mixed up some how and came up with a brillant
red mixture. The English not being chaps to tolerate
such a slip gave him the sack - as they say.
He took his formula to a paint company, produced very
good red paint and became rich. Nearly every artist
today uses a range of these paints.
The WWW has this to say
Cascara sagrada has a long history of traditional use
by native americans. Cascara sagrada contains
compounds called anthroquinones, which are responsible
for cascara's powerful laxative effects.
Anthraquinones trigger contractions in the colon,
called peristalsis, which causes the urge to have a
bowel movement. Today, it is one of the most common
herbal laxatives. 
So prehaps buckthorns were introduced here by the
French for medecinal purposes as well.
Enjoy the rest of the summer
Paul
