Magnolia virginina aka Sweet Bay Magnolia was widely used as medicine among Native Americans and early Americans. It is still used for various ailments today. You can find it for sale on the internet. Magnolia spp grows all around the world.
Tommie Bass, the now deceased highly sought-after Alabama herbalist, said more people came to him for Magnolia spp to treat arthritis, joint pain, and gout than any other plant. He said it did not work for everyone, but it did work for many. In fact, medical doctors in the early 1800s considered it a very effective treatment for rheumatism and arthritis.
The bark contains two polyphenols: magnolol and honokiol. Magnolol is an antihistamine. By reducing the histamine release, magnolol can help alleviate symptoms associated with allergies, such as inflammation, itching, and swelling. Magnolol supports the body's natural production of adrenal steroids which gives it antispasmodic effects. Honokiol is a muscle relaxer that appears to be five times more effective at relieving anxiety than some Rx medications. That's impressive!
Magnolol and honokiol relax bronchial muscles, making it easier to expel mucus, thus contributing to its expectorant properties. These help reduce inflammation in the respiratory tract, assisting with conditions like asthma or bronchitis. Magnolol and essential oils in Magnolia virginiana help stimulate the respiratory system to expel mucus. The alkaloids in the tree work as bronchodilators to ease breathing. These things can make it a good option for respiratory ailments.
The leaves are used as a vulnery meaning it helps heal wounds. The antimicrobial properties promote healing and prevent infection. The leaves were used as a poultice.
The Native Americans used the largest leaves of Magnolia to wrap their food. They also used the leaves as a spice to flavor their foods like gravies. The Rappahannock used it as a mild stimulant. The bark is a chief food for beavers, so it was also known as the Beaver Tree. In Japan, they use the leaves as a dish to grill foods on.
In China, Magnolia obovata, is used in over 200 patent medicines. One paper I read said many of the Chinese in America buy Magnolia bark and extracts available because they know how valuable the tree is for medicine. While you can use different species of Magnolia, the chemical compounds may vary by species.
