Furanocoumarins: Furanocoumarins have sun- or
photosensitizing properties and are often used for the treatment of skin
conditions sometimes with controlled exposure to the sun.
Other effects of Furanocoumarins reportedly are: hypotensive activity,
antiasmatic and antispasmodic.
Furanocoumarins are potentially photo-carcinogenic and may promote a cancer that
is initiated by interference with the skins natural ability to protect
underlying cells against the carcinogenic effect of harmful ultra violet
radiation.
Furanocoumarins are Coumarins with a furan ring

Coumarins: Coumarins are lactones of hydroxycinnamic
acids. Coumarins are lactones. There are many variations of coumarins: Furanocoumarins found in Angelica have a
spasmolitic effect but must be used with caution as they have a strong
phototoxic effect as has many of the Furanocoumarins (Warfarin a blood thinning
drug but also virulent rat poison, is a coumarin derivative). In general
coumarins have antifungal, hypotensive, anticoagulant and antimicrobial properties.
Many of the Coumarins are phototoxic and skin sensitising.
Lactones: A lactone is an Ester that's
functional group has become part of a ring structure with carbon atoms.
Lactones are widely present in the plant kingdom and many are expectorants and
febrifuges. |
