Therapeutic Uses, Benefits and Claims of Grindelia
Grindelia has a calming effect on the heart muscles, which makes it effective in the natural treatment of asthma and bronchial conditions, particularly when these are linked with an increase in the rate at which the heart beats and nervous response.
It is also used an herbal remedy for whooping cough and respiratory catarrh.
It is a potent expectorant, which helps clear up severe congestion that occurs in the case of chronic bronchitis, asthma and emphysema.

Grindelia has also been used for a long time as a remedy for dermatitis caused by poison oak or poison ivy.
The latter belong to the genus of Toxicodendron and contain a strong resin, urushiol, which causes a severe allergic reaction in case of contact with skin.
The plant was used for this purpose by the Native Americans and also in pharmaceutical medications in the early 1900’s. Application of the tincture on the affected area will provide relief.
Topical preparation of this herb can also be used to soothe burns, insect bites, and skin rashes.
The active compounds in the herb include resins; flavonoids such as kumatakenin and acacetin; and diterpenes of the grindelane type.
Grindelia can be consumed as an infusion, which can be easily prepared by boiling one cup of water and soaking one teaspoon of the dried herb in the water for ten to fifteen minutes.
The infusion should be consumed thrice a day.
Alternatively, in the form of tincture, 1-2 ml should be taken three times a day.
