Wound healing, blood vessel dilation

Oil or water infusions, fresh poultices, or commercial gels.

Used for closed-tissue injuries, such as fractures, sprains and contusions.

When applied topically, arnica acts to dilate the peripheral capillaries to increase tissue circulation and decrease inflammation. It helps speed the healing process by removing waste fluids and bringing clean fluids into the affected area.

Apply enough infusion or gel to wet the skin of the animal, then wrap the area with gauze. Ensure the gauze is well secured so the animal cannot remove it. Apply twice daily for up to 3 days.

• Long-term external application of arnica is not recommended, because it can cause a rash.
• Do not apply to bleeding, open wounds.
• Special care must be taken that dogs do not lick off arnica, as it can be toxic at improper dosages and can cause internal bleeding.
• Cats can be prone to allergic reactions to arnica, so test a small portion of the skin first. Check for redness or signs of irritation before using on an injury.
