Common Uses in Dogs

This herb is an effective anti-inflammatory, due to the presence of Glycyrrhizin, which has a similar chemical structure to that of natural corticosteroids released by the adrenal glands. Glycyrrhizin stimulates the adrenals and is useful for treating Addison's disease.

The herb also acts on the digestive system by promoting cell growth and alleviating ulcers.

It is also beneficial in treating liver toxicity.

For the upper respiratory tracts, licorice root has long been used to alleviate coughs and ease discomfort brought on by bronchitis. This is largely due to its demulcent, anti-flammatory, and expectorant properties.

To treat or prevent any of the above ailments, the best way is to feed your dog tinctures of the herb.

Topically, because of its anti-inflammatory, antimicrobial and antiarthritic properties, this herb is excellent in helping to alleviate pain, reduce joint swelling and ease some skin conditions, such as eczema, contact dermatitis, and flea allergies. In this case, an oil infusion of the herb can be applied to the affected areas.

Precautions

Licorice can raise sugar levels in blood and should be used with caution in diabetic dogs. Also do not use licorice for dogs with heart disease.

The plants are available at most nurseries. Various preparations (such as tincture, tea, oil infusion) are available at health food stores. References
