What is Black Willow Bark Extract?

Black willow bark extract comes from, not surprisingly, the willow tree, which is native to eastern North America. “Willow bark contains the active ingredient salicin, which is a similar active to salicylic acid,” says Mona Gohara, MD, a dermatologist in New Haven, CT. “It is not salicylic acid but a relative of it.” When ingested, the salicin is converted into salicylic acid via the digestive process — which, incidentally, is the primary ingredient in aspirin. For that reason, practitioners of native and folk medicine have long sought it out to treat pain and inflammation.

The Black Willow (Salix nigra) is native to the eastern US. The bark contains high levels of salicylates and tannins. These compounds have been used traditionally in skin care for their astringency and anti-inflammatory characteristics.

Black Willow Bark benefits

Black Willow Bark Extract Benefits:

1.Pain relief

Black 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 synthesised 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.


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.

3.Heart Health

Black Willow Bark Extract 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.

4.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.

5.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.


1.Applied in cosmetics, it can inhibit whelk and relieve swelling and pain.
2.Applied in pharmaceutical field, it is mainly used to curing fever, colds and infections.
3.Applied in feed additive, it is mainly used as feed additive for diminishing inflammation and promoting digestion.

Willow bark extract dosage

Black Willow Bark Extract dosage

Willow is available in several dosage forms, including tablets, capsules, powder, and liquid. Willow bark has been used for analgesia at daily doses of 1 to 3 g of bark, corresponding to salicin 60 to 120 mg. A clinical study of patients with lower back pain used willow bark at a salicin dose of 120 to 240 mg/day. A proprietary extract of willow bark, Assalix, was standardized to contain 15% salicin. The pharmacokinetics of salicylic acid delivered from willow bark have been studied, and plasma half-life is approximately 2.5 hours. Another pharmacokinetic study of salicylic acid from salicin found peak levels within 2 hours after oral administration.
