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].
Other Uses
Dye;  Hair;  Parasiticide.

Yellow and green dyes are obtained from the flowering heads and pods[168]. Aromatic. A decoction of the roots has been used as a hair shampoo to kill lice[257].
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.
Propagation
Seed - sow autumn or spring in a cool greenhouse and only just cover the seed. Prick out the plants into individual pots when they are large enough to handle and plant them out into their permanent positions in early summer.

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.
