Typha latifolia

Typha latifolia pollen contains active compounds including typhasterol, isorhamnetin, quercetin, and naringenin that contribute to its hemostatic effects. These compounds appear to support blood vessel integrity and promote blood clotting through anti-inflammatory and astringent properties. In Traditional Chinese Medicine, the pollen is believed to invigorate blood circulation while simultaneously stopping bleeding. The exact mechanism requires further research, but the flavonoid content likely plays a key role. Evidence level: C.

Typha latifolia may interact with anticoagulant and antiplatelet medications due to its blood-clotting properties. Taking it alongside blood thinners like warfarin, aspirin, or clopidogrel could potentially reduce their effectiveness. Additionally, because raw forms affect bleeding disorders, combining it with other herbs that influence blood clotting could produce additive effects. Patients on anticoagulant therapy should avoid this herb unless supervised by a qualified healthcare provider. Evidence level: C.

Traditional dosage recommendations for Typha latifolia pollen powder range from 3-10 grams daily when taken internally. For tea preparations using the plant material, 5-15 grams may be used. Dosage should be individualized based on the specific condition being addressed and personal tolerance. Those new to this herb should start with lower doses to assess tolerance. Consult a qualified herbalist or healthcare provider for personalized dosing guidance. Evidence level: Traditional.

Typha latifolia is considered unsafe during pregnancy. Traditional use and pharmacological evidence suggest it stimulates uterine contractions, which could potentially lead to miscarriage or premature labor. Pregnant women should avoid all forms of this herb, including pollen powder and tea preparations. Women who are breastfeeding should also exercise caution, as safety data for lactation is limited. Evidence level: C.

Typha latifolia has been used globally in traditional medicine systems. In Traditional Chinese Medicine, the pollen—known as Pu Huang—is primarily used as a hemostatic agent to stop bleeding and invigorate blood circulation. It has been traditionally applied to reduce swelling, treat wounds, and address various inflammatory conditions. Indigenous peoples across North America have also used various parts of the plant for wound healing and as a nutritious food source. Evidence level: Traditional.
