Skullcap Overview
Skullcap is a perennial herb native to North America. It is a member of the mint family and has small, blue or purple flowers that bloom in the summer. The plant is named for its shape, which resembles a small, hooded skull.
Skullcap is often used in traditional medicine to treat a variety of conditions, and some studies have suggested that skullcap may have sedative and anxiety-reducing effects.
American skullcap (Scutellaria lateriflora) Baikal skullcap (Scutellaria baicalensis) are two different plants that are often referred to simply as "skullcap." but they belong to different species and have different medicinal properties.
Morphine Sulfate Overview
-
Morphine is used to relieve moderate to severe pain. Morphine extended-release tablets and capsules are only used to relieve severe (around-the-clock) pain that cannot be controlled by the use of other pain medications. Morphine extended-release tablets and capsules should not be used to treat pain that can be controlled by medication that is taken as needed. Morphine is in a class of medications called opiate (narcotic) analgesics. It works by changing the way the brain and nervous system respond to pain.
