Black Haw (Viburnum Prunifolium) Tincture, Bark

Both are liquid extracts of the same Viburnum prunifolium bark; only the solvent differs. The tincture uses alcohol as the traditional solvent, with vegetable glycerin and water. The alcohol-free version is a glycerite made with vegetable glycerin and purified water, suited to those who avoid alcohol. Both deliver the bark's constituents in a convenient liquid you take by the drop. Choose the tincture for a classic alcohol-extracted format with a longer shelf life; choose the glycerite if you prefer no alcohol. See the safety note below.

No, though the names cause confusion. Black haw is Viburnum prunifolium, and it is a close botanical relative of cramp bark, which is Viburnum opulus (also called guelder rose). The two are different species in the same genus and are often used similarly and even substituted for one another, so it helps to know that our product is specifically black haw, Viburnum prunifolium. Black haw is also sometimes nicknamed "American cramp bark," which adds to the mix-up. Separately, black haw is not the same as hawthorn (Crataegus), which is a different genus entirely - the shared word "haw" is just a coincidence of naming. It is also distinct from the ornamental viburnums grown in gardens. We label our product clearly by botanical name (Viburnum prunifolium) and plant part (bark) so there is no confusion with cramp bark, hawthorn, or the garden shrubs.

Shake well before use. Use the number of drops and the frequency shown on the label, in a little water, tea or juice, or as directed by your practitioner. Please read the important safety note below before use. Drink the entire contents.

Please read this carefully, because black haw has a few important safety considerations. Black haw naturally contains salicin, an aspirin-like compound, so do not use it if you are allergic or sensitive to aspirin or salicylates, and use caution if you take blood-thinning medication. For the same reason, do not give black haw to children or teenagers, especially during or after a viral illness, because of the risk associated with salicylates in young people. Black haw also contains oxalates, so use caution if you have a history of oxalate kidney stones. Black haw has a long traditional association with the female reproductive system, and while it has historically been used in pregnancy, it should not be used during pregnancy without the direct supervision of a qualified healthcare practitioner; it is best avoided while nursing as well unless directed. If you take any medication or have a medical condition, also consult a qualified healthcare practitioner before use. Keep out of reach of children and do not exceed the suggested serving. Discontinue use and consult your practitioner if any adverse reaction occurs. These statements have not been evaluated by the Food and Drug Administration.
