Arnica (Arnica montana)

Corydalis (Corydalis yanhusuo)

About

Arnica is an aromatic perennial, usually about 1 ft (30 cm) high, with downy, oval-shaped leaves and bright yellow daisy-like flowers. Well-known for reducing swelling, bruising, and pain from injuries, it is frequently used as a homeopathic remedy (both internally and topically) for bruises, sprains, and sore muscles. Higher-dose tinctures have a stronger anti-inflammatory action and may serve as a cardiac tonic by improving blood flow to the coronary vessels, but such usage must be closely supervised.

Corydalis is a small herbaceous perennial growing to 8 inches with narrow leaves and pink flowers. Native to Siberia, northern China, and Japan, it is commonly cultivated in eastern and northeastern parts of China. Propagated from seed in early spring or autumn, the rhizome is harvested in late spring and early summer when the aerial parts have withered. This important Chinese remedy has been used at least since the 8th century to help 'invigorate the blood' and relieve almost any painful condition, particularly menstrual cramps and chest and abdominal pain.

Safety & precautions

Toxicity (internal use): Arnica tincture can be toxic even at low dosages and should only be taken under professional supervision and in a highly diluted form. Skin application: Neither the herb nor homeopathic arnica should be applied to broken skin. Extended external use may cause dermatitis in sensitive people due to the sesquiterpene lactones it contains. Pregnancy & Nursing: Should not be used internally during pregnancy or while nursing. High Doses: Can lead to symptoms such as dizziness, tremors, irregular heartbeat (tachycardia, arrhythmia), and possibly collapse. Legal Restrictions: Arnica is subject to regulatory controls in certain countries.

Do not take during pregnancy. Generally well-tolerated when used as directed. The alkaloid content provides effective pain relief but should be used responsibly.
