Magnolia (covering more than 200 different species within the Magnoliaceae family of flowering plants) has a strong history. This ancient flowering plant has been on Earth as far back as 95 million years ago during the Cretaceous period. Studies show that although there were dinosaurs at that time, bees still did not exist. Pollination of the magnolias evolved by ancient insects; today we know them as beetles.
Historically used in traditional Chinese medicine, today you will find magnolia regarded as an herbal remedy around the world. Magnolia bark, commonly from the Houpo Magnolia tree, is shredded to make the supplements we use today. It is also common to see the flowers and leaves being used.
Various extracts derived from Magnolia bark are “widely available in dietary supplement products at recommended doses of 200 to 800 mg/d per person. Magnolia ingredients have indisputably a wide variety of pharmaceutical properties” (1).Credited for magnolia’s medicinal properties: Magnolol and Honokiol, both in the polyphenol category. They are known for their antioxidant benefits, and offer support in many health categories. Magnolia’s antimicrobial activity delivers benefits in the dental health arena. Magnolol is known to provide support for gum disease, bad breath, and cavities, and is used in a gum for halitosis.
Magnolia also is known to fight oxidative stress, and to help ease stress. It seems to be more effective for menopausal women, and there have been success stories in the areas of menopausal symptoms including anxiety, depression, and mood lifting.
As always, one should discuss the use of supplements with a medical practitioner. Because it is shown to have circulatory benefits, magnolia is not recommended for those who are using a blood thinner, or are pregnant or breastfeeding.
