Our tinctures are made using the classic tincturing method. The tinctures are made in a 1:4 ratio which allows for the optimal extraction of the herb. The alcohol percentage is strictly controlled depending on the part of the plant that is used for the tincture. We have 50ml bottles (with a dropper), 100ml bottles (with a pipette) and a 1L bottle. Extraction ratio : 1/4 Ingredients: Alcohol, distilled water, and dried Pine Needles Alcohol volume: 50% We also offer a non-alcoholic version of this tincture (with glycerine).
