Parthenolide is a bioactive sesquiterpene lactone isolated from Feverfew (Tanacetum parthenium) and select Magnolia species (e.g., Michelia hedyosperma). It exhibits potent anti-tumor, anti-inflammatory, and anti-leukemic properties by selectively targeting cancer stem cells and inhibiting NF-κB signaling pathways. This 98% high-purity extract is optimized for pharmaceutical R&D and nutraceutical applications, ensuring batch-to-batch consistency through advanced purification technology.
