Marsdenia tinctoria
Marsdenia tinctoria
Marsdenia tinctoria, commonly known as alkanet, is a flowering plant native to tropical and subtropical regions. Traditionally, its use has not been documented in any specific medical practices or cultural traditions. Scientific studies have shown that the plant's extracts can stain lipids red and certain tissues blue due to their chemical properties, but this finding does not pertain to medicinal uses. The dense floral hairs of Marsdenia tinctoria primarily serve to filter out smaller insect visitors, facilitating pollination by larger insects such as wasps. In laboratory tests, the ethyl acetate fraction (ATiEA) and its sub-fraction ATiEA-II from Marsdenia tinctoria demonstrated significant anti-inflammatory activity in 5-LOX inhibition assays, though further research is needed to confirm these findings. No major safety issues or drug interactions have been recorded for this plant.

What the science says
- The ethyl acetate fraction of Marsdenia tinctoria (ATiEA) and its sub-fraction ATiEA-II showed significant anti-inflammatory activity in 5-LOX inhibition assays.
- The study found that extracts from alkanet can stain lipids red and certain tissues blue, depending on the solvent polarity and pH.
- The dense floral hairs in Marsdenia tinctoria primarily filter out smaller insect visitors, facilitating wasp pollination.
- Some evidence supports a single origin of pyrrolizidine alkaloids, while other evidence suggests multiple independent origins.
