Decursinol-50 is obtained from the roots of the herb Angelica gigas Nakai, also known as Korean Angelica. This plant was used over a thousand years back from today. It is used for pain relief, and is prepared by a process in which whole dried roots are extracted using alcohol, thus giving a highly concentrated root component, containing decursin and decursinol. Research has shown that Decursinol-50 is useful for minor pains. Studies done on animals show that this compound has analgesic properties, by affecting the opioid receptors of the central nervous system. Supplements of Decursinol-50 can be taken and one capsule daily can be consumed without any side effects.
