cramp bark

Formulas often use a cramp‑bark alternative such as Black Haw paired with calming botanicals — for example, Valerian root, Black cohosh, Ginger root, and sometimes Garrya.

They are sold as concentrated liquid herbal formulas (liquids/tonics) and as capsules.

Most list “Suggested Age: Adult” and include a warning such as “Do not use if you are pregnant or nursing.”

Commonly listed nutrients include Vitamin B3 (niacin), Vitamin C, Rutin, Calcium, Magnesium, Vitamin B6, and Vitamin E.
