Health Benefits & Sources
Why You Need It
- Supports Healthy Circulation: Helps widen blood vessels (vasodilation) for better blood flow.
- Respiratory Relief: Acts as a natural expectorant, helping to clear mucus from the lungs.
- Antioxidant Protection: High tannin content fights oxidative stress in the body.
Deep Dive
Quebracho contains a high concentration of proanthocyanidins (a type of flavonoid) and tannins. These compounds are the heavy lifters here. They work by stimulating the release of nitric oxide, a molecule that relaxes the inner muscles of blood vessels, allowing them to widen. This mechanism is particularly beneficial for circulation. Additionally, the astringent properties of the tannins help tighten and dry out mucous membranes, which can assist in clearing congestion from the respiratory tract. It is a classic herbal remedy for chronic respiratory conditions.
Natural Food Sources
Quebracho is a specific tree bark extract; it is not found in common fruits or vegetables. However, you can find similar beneficial proanthocyanidins in the following foods:
| Food | Amount | % DV |
|---|---|---|
| Dark Chocolate (85%+) | 1 oz (28g) | ~5% of Daily Value |
| Blueberries | 1 cup | ~3% of Daily Value |
| Green Tea | 1 cup | ~2% of Daily Value |
| Red Wine | 5 oz glass | ~1% of Daily Value |
Supplementation
Since you cannot eat enough Quebracho tree bark to get a therapeutic dose, supplementation is the standard route. Look for dry extracts standardized to contain roughly 80-90% tannins (often called quebrachol). It is typically taken in capsule or liquid tincture form. Standard dosing usually ranges from 300mg to 600mg daily, but always follow the manufacturer's instructions as potency varies.

Safety & Side Effects
Safety First
Quebracho is generally considered safe when used at recommended dosages for short periods. However, because it is rich in tannins, it can cause stomach irritation, nausea, or kidney irritation if taken in excess.
Who should avoid it?
- Pregnant or breastfeeding women: There is insufficient safety data.
- People with kidney disease: Tannins can be hard on the kidneys.
- Iron deficiency anemia: Tannins can inhibit iron absorption; take at least 2 hours apart from iron supplements.
Always consult a healthcare provider before starting a new supplement regimen.
