Plant sterols (phytosterols) can be removed from many plants. Beta-sitosterol can be extracted from Sea buckthorn seeds. Such natural chemicals have medicinal effects which are more effective with fewer side effects than synthetic chemicals. Such sterols are found in saw palmetto leaves, dandelion leaves and chaste tree leaves.
Plant sterols are used in cancer treatment. Phytosterol rich cooking oils can help people lower blood cholesterol. The plant sterols are anti-inflammatory, anti-bacterial, anti-ulcerative, and anti-tumor.
The author describes a “supercritical carbon dioxide extraction technique” for obtaining the maximal amount of plant sterols from the herbs.
