Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.


According to Rahman et al. (2011) B. frondosa is potentially a useful source of essential oil extracts with antibacterial and antioxidant properties. Infusions and tinctures of B. frondosa have a wide range of medicinal properties. They can be used for treatment of irritation, inflammation, pain and bleeding of the urinary tract mucosa and are used for benign prostatic hypertrophy and increasing excretion of uric acid and decreasing the risk of gout attacks (Flora of North America, 2014) [1d].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Cultivation details

We have very little information on this species and do not know if it will succeed outdoors in Britain, though judging by its native range it should succeed in most parts of the country when grown as a spring-sown annual. The following notes are based on the general needs of the genus. Succeeds in any moderately fertile moisture-retentive soil in full sun[200].

Seed - sow early spring in a greenhouse and only just cover the seed. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in May. Alternatively, a sowing in situ in mid to late spring can be tried.

Weed Potential

Right plant wrong place. We are currently updating this section. Please note that a plant may be invasive in one area but may not in your area so it’s worth checking.

The majority of introductions into new countries are intentional, due to the medicinal, herbal and decorative properties ascribed to the species. However, seeds can be accidentally dispersed into new areas as they can adhere firmly to animal fibres such as wool. In Europe B. frondosa has been reported to outcompete and interbreed with native plant species in particular those of the same genus. B. frondosa is classified as an environmental weed in New Zealand [1d].

Common vegetable & medicinal plant (doesn't say what for) in Africa (From"An Illustrated Guide to Common Weeds of New Zealand"). One seems to have smuggled itself into my garden with some purchased nursery plants, lucky me! Growing in a spot with very little sun.

I am currently studying herbal medicine outside of Asheville, NC at Blue Ridge School of Herbal Medicine. My teacher, CoreyPine Shane, uses this species of Bidens as a decongestant, and in this way it is similar to Ragweed, Ambrosia artemisifolia. I find Bidens frondosa to work more strongly as a decongestant than Ambrosia.
