(Grindelia squarrosa)
extracted by tincture in food grade alcohol

Expectorant / Antispasmodic / Anti-inflammatory

Plant Description/History: Grindelia squarrosa, also known as “Curlycup” Gumweed, belongs to the family Asteraceae (Compositae) and is indigenous to much of the United States.

Constituents-Chemicals & Nutrients: Grindelia may contain as much as 21% of amorphous resins. As well as tannin, laevoglucose, and a little volatile oil. The presence of glucosides has not been confirmed. Other active compounds include flavanoids such as kumatakenin and acacetin; and diterpenes of the grindelane type.


Useful in asthmatic and bronchial conditions as a potent expectorant and antispasmodic, Gumweed also acts to relax smooth muscles and heart muscles. This helps to explain its use in the treatment of asthmatic and bronchial conditions, especially where these are associated with a rapid heart beat and nervous response. Because of the relaxing effect on the heart and pulse rate, there may be a reduction in blood pressure.

The Gumweed tincture may also be used topically to keep poison oak and poison ivy rashes from spreading.

Dosage for Adults: 20 to 30 drops (1 to 2 ml) taken two to three times a day as needed for asthmatic and bronchial conditions.

Warnings: Prolonged use of Gumweed can cause irritation in the stomach or kidney.
