Our Lion's Mane tincture is made with Lion's Mane that we foraged for and harvested. We add the mushroom to glycerin and alcohol and allow it to infuse over a period of time, using no heat. Each bottle of tincture is 1 oz and comes with a glass dropper. Tincture can be taken sublingually, added to teas and coffee, and added to foods. May help with brain activity and function.
