Traditional Uses
Wild Marigold has been traditionally used for digestive health, urinary tract health, and pain and inflammation, among other applications.
Digestive health.
- Stomachic
- Carminative
- Dyspepsia
- Purgative
- Vermifuge
For digestive complaints, the herb is typically prepared as a tea or decoction taken before meals. The bitter compounds stimulate digestive secretions and improve nutrient absorption. Some traditions use the powdered root or leaves in small doses as a stomachic tonic.
Urinary tract health.
- Diuretic
Urinary tract applications typically involve drinking the herb as a mild tea, which increases urine production and helps flush the urinary system. It may be combined with other demulcent herbs to soothe irritated tissues.
Pain and inflammation.
- Inflammation
- Swelling
For pain and inflammation, preparations are applied both topically as compresses and taken internally. A warm poultice draws blood to the area and promotes healing, while internal preparations address systemic inflammation.
