Arnica (Arnica montana) vs Myrrh (Commiphora molmol)

Arnica (Arnica montana)

Myrrh (Commiphora molmol)

About

Arnica is an aromatic perennial, usually about 1 ft (30 cm) high, with downy, oval-shaped leaves and bright yellow daisy-like flowers. Its flowers and roots have traditionally been used for bruises, sprains, arthritic pain and muscle aches, and a highly diluted form is used in homeopathy; MSK says a few clinical trials suggest topical arnica may help osteoarthritis and bruising, but rigorous research on homeopathic arnica is still needed. Arnica taken internally can be toxic (see precautions).

Myrrh is a resin obtained from several Commiphora species, notably C. myrrha, recognized by its thick, yellowish-red gum resin. It is bitter in taste and aromatic.

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.

Pregnancy: Should not be used internally; it can stimulate the uterus. Essential Oil: Not advisable to ingest without professional supervision; can be irritating if used improperly.
