Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

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.
Antispasmodic  Blood purifier  Demulcent  Expectorant  Parasiticide  Sedative  Stomachic

The leaves and flowering tops are antiphlogistic, antispasmodic, balsamic, demulcent, expectorant, sedative, stomachic and a vascular tonic[4, 7, 21, 46, 61, 207, 213]. Blood purifier[4]. The plant is applied externally as a compress on inflamed or irritated areas of the skin[7, 257]. Used internally, it slows down the heartbeat and reduces the stimulation of the nerve endings in the air passages that causes coughing - it is therefore extremely effective as a calming agent in the treatment of asthma[7]. The fluid extract is prepared by placing the freshly gathered leaves and flowers in a small quantity of simmering water for about 15 minutes[213]. The plant is used to treat people affected by poison-ivy[213].

Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Special Uses

Cultivation details

Succeeds in any well-drained soil in full sun[200]. Does well on dry sandy banks and in poor soils[200]. Plants tend to concentrate selenium in the leaves and stems, this is especially noticeable on soils that are relatively rich in that element[21]. Some authorities class this species as a synonym of G. camporum.

Thanks for the info. I found this site useful as I was researching Grindelia Robusta as an active ingredient in a commercial poison ivy scrub.
