Our 900mg PM formula is blended with hops, sweet orange and roman chamomile and is perfect for evening use. We like to use this tincture to aid sleeping*, to manage chronic pain*, help quell headaches, and to maintain overall wellness. We suggest use of about 30mg, once in the evening. One droplet of PM contains 1.5mg of extract, making 20 droplets your evening dose (about 1/2 dropper-full). This bottle provides about a 30-day supply dependent upon how often it's taken.
