Traditional Use and Health Benefits

Native to Europe and Central Asia, the bark of the White Willow tree has been used for over 5,000 years as a powerful pain relief remedy. The Ancient Egyptians used this bark to treat pain and inflammation, whilst Hippocrates and Dioscorides recommended it as a remedy for gout and rheumatic joint diseases. Native American healers also relied on White Willow bark for its analgesic properties.

White Willow Benefits

Pain Relief Willow’s active chemical constituent – salicin – was identified in 1829 by the French pharmacist H Leroux. Whilst this chemical is a powerful anti-inflammatory and analgesic, studies show several other components of Willow bark (including polyphenols and flavonoids), have antioxidant, fever reducing, antiseptic and immune boosting properties. Some studies show that this plant is as effective as aspirin for reducing pain and inflammation at much lower doses.

It has been shown to relieve headaches and is less likely to cause gastrointestinal side effects than synthesized pain relievers such as ibuprofen. Those who suffer from chronic and/or recurring headaches are strongly advised to seek help from their healthcare professional. In a well designed study of 200 people with lower back pain, those who received White Willow bark experienced a significant reduction in pain compared with those who received a placebo. Furthermore, people who received higher doses had more significant pain relief.

Arthritis The active components in White Willow bark have been shown to inhibit cyclooxygenase – an enzyme responsible for inflammatory mediators like prostaglandins. Salicin will also ease the discomfort, further reducing the production of prostaglandins in the nerves and its anti-inflammatory properties help in reducing painful inflammation of the joints. It is thought that regular intake of White Willow bark will help to suppress the progression and onset of arthritis.

Heart Health It is well known that low doses of aspirin are taken as a preventative as well as first aid for a heart attack as it helps to reduce the risk of internal clotting. Since the salicylates in aspirin are derived from Willow bark it stands to reason this herb has the same effect on the heart as aspirin. This means it can be effective in reducing the risk of heart attacks and strokes.

Menstrual Cramps Painful menstrual cramps are usually the result of inflammation of the uterine lining and the contractions which are triggered by prostaglandins. As we know Willow bark regulates the production of prostaglandins and reduces inflammation, it will help to soothe not only cramps but other PMS symptoms. The only side effect to using this remedy could be an increase in the flow of blood due to its blood thinning effects.

Skin Health Powerfully antioxidant compounds found in White Willow bark have been found to have a very positive effect on the skin. It increases the blood flow to the skin, thus providing much needed nourishment, and can reduce the appearance of wrinkles and age spots.
