One of the most common uses for pine needles and spruce tips throughout history has been to soothe sore throats and coughs while also acting as an expectorant (helping the body to thin and remove mucous). Various clinical studies have supported the use of coniferous products for different immune challenges:
The Vitamin C content of the spruce tips and pine needles we use to make our Evergreen C Tincture should not be underestimated. You may think that keeping your Vitamin C levels high is as simple as downing a packet of EmergenC - but that is not the case.
Synthetic Vitamin C supplements (as well as the vast majority of ‘immune boosting/cold supplements’ available) utilize ascorbic acid, an inferior form of this nutrient with poor bioavailability and limited effects on health. Ascorbic acid is produced in a lab, mostly from GMO corn sugar glucose. Calling ascorbic acid Vitamin C is like calling the orange peel the whole orange - ascorbic acid is best thought of as the antioxidant skin of the entire Vitamin C complex.
According to the clinical research of Dr. Royal Lee, considered the Father of Holistic Nutrition, isolated ascorbic acid failed to bring complete systemic relief to scurvy as he did when using whole foods.
