Wild Cherry

Christopher Hobbs:

“Wild cherry bark has a long history of use as an ingredient in cough syrups and is used particularly for dry, nonproductive, and irritating coughs and pleurisy. It is also beneficial for nervous dyspepsia and lack of appetite. Wild cherry contains prunasin, a cyanogenic glycoside, which gives it its antispasmodic and sedative properties, but might make it toxic in large amounts or when taken for longer than several weeks. The remedy is especially indicated for dry, chronic cough with deficiency or productive cough with yellow sputum.
The bark should be used as freshly dried as possible. Soak 4 ounces of the bark in 4 ounces of water for several hours, strain, sweeten with a little honey, and take 2-3 teaspoonfuls, 2-3 x daily. Make a decoction by simmering 4 grams of the bark in 4 ounces of water for a few minutes; let steep for 15 minutes, strain, sweeten to taste, and drink 1/2 cup, 2-3 x daily. As a tincture, put a teaspoon in a little water and sip on it throughout the day.

Wild Cherry has a taste of BITTER, SWEET and a temperature of COOL.”

Historical Uses

Wild cherry (Prunus serotina) has a long history of medicinal use by Native Americans and early settlers. The bark was traditionally used to treat coughs, colds, bronchitis, and digestive complaints. It was often included in syrups and teas for its soothing and sedative properties.

Modern Clinical Uses

Herbalists and naturopaths use wild cherry bark primarily as an antitussive (cough suppressant) for dry, irritating coughs. It’s also employed for mild bronchial spasms, asthma, and inflammation. Some practitioners incorporate it into formulas for digestive health or as a mild sedative.

Chemistry

The key active compounds in wild cherry bark include:

• Cyanogenic glycosides (e.g., prunasin): These release small amounts of hydrogen cyanide when metabolized, which provides a mild sedative effect on the respiratory system.
• Flavonoids: Antioxidant and anti-inflammatory properties.
• Tannins: Contribute to its astringent and soothing effects.
• Volatile oils: Minor components with potential therapeutic activity.

Pharmacology

Cyanogenic glycosides are central to wild cherry bark’s effects. In small doses, these compounds reduce coughing by relaxing the smooth muscles of the bronchi. The bark’s tannins have astringent properties that may help soothe throat irritation. However, the presence of cyanogenic compounds necessitates careful dosing to avoid toxicity.

Clinical Trials

Clinical research on wild cherry bark is limited. Most evidence for its efficacy is anecdotal or derived from traditional use. Few trials have examined its effects, with small studies suggesting mild benefits for cough suppression. However, more robust, controlled trials are needed to confirm these findings and better understand its pharmacological mechanisms.

Summary

Wild cherry bark is a well-known herbal remedy historically used for respiratory and digestive issues. Modern herbalists employ it primarily as a cough suppressant and respiratory aid, though its use requires caution due to the potential for toxicity. Its active constituents and effects are well-documented in herbal medicine, but clinical evidence is sparse, warranting further research.
