Canaigre: What it is and why people ask about it
Canaigre (often called canaigre dock or Rumex hymenosepalus) is a desert plant known for high tannin content. People have used it for dyes, leather tanning and, in some traditional systems, for mild digestive or topical uses. If you’ve seen the name on a supplement label or heard about it from a friend, this page gives straight facts: what people use it for, what the evidence says, and how to stay safe.
What people use canaigre for
Most interest in canaigre comes from two areas. First, its tannins are useful in industry—dyeing and tanning hide. Second, some herbalists use small doses topically or orally for minor skin issues or as an astringent (a substance that can tighten tissue). People sometimes consider it for digestive complaints, but reliable human studies are limited.

Safety, dosing, and buying tips
Research on canaigre for medical use is sparse. That means there’s no well-established safe dose for treating any condition. Don’t assume “natural” equals harmless. Tannins can irritate the gut in some people, and topical use may trigger contact reactions if you have sensitive skin.
If you’re thinking of trying canaigre:
- Talk to your doctor first—especially if you’re pregnant, breastfeeding, on blood thinners, or have liver or kidney problems.
- Start with a low amount if you try a topical product. Stop if you get redness, itching, or stomach upset.
- Buy from reputable sellers. Look for third-party testing and clear labeling. If a supplier makes strong medical claims, treat that as a red flag.
