When you want to relax, Reishi is the mushroom to turn to, as it helps the body de-stress and can help normalize sleep cycles. It’s been used in traditional eastern medicine for thousands of years, and is a rare woody fungi originating from Asia. Known as the “King of Herbs,” Reishi is thought to support the immune system and fight viral and bacterial illnesses, thanks to its beta-glucans (immune system-boosting sugars). Studies even indicate that its compounds may help slow the spreading of cancer cells, although more human testing needs to be done to confirm its effectiveness. According to holistic nutritionist Natasha Upensky, Reishi also helps to balance blood sugar, making it good for diabetic conditions and weight loss. Adding Reishi to your bedtime routine can also have a nice relaxing effect.
