At Canadian pine pollen Co. we make our Pine Pollen tincture from 100% fresh raw pollen that is wild harvested in British Columbia. We use pure pollen, not the buds. We do not import our pine pollen from China, so you can be sure your pollen is locally wildcrafted in our pristine Canadian high altitude mountains, and that it is always fresh, and has never been heat treated or microwave sterilized. We use a proprietary dual extract method to concentrate the androgens as well as the flavonoid and other water soluble antioxidants. We do no use heat. So you can be sure what you get in the bottle is an extract from the wild, raw, and living pine pollen, in its purest form and as nature had intended it; potent.
