Christopher Hobbs:
“Loquat leaves expel phlegm from the lungs and allay coughing. In Chinese medicine loquat leaves are said to clear heat from the stomach and are used for vomiting, nausea, and belching.
Loquat has a taste of BITTER and a temperature of COOL.”
Historical Uses
In ancient Chinese and Japanese practices, loquat leaves and fruits were used to treat coughs, respiratory infections, skin issues, and digestive concerns. Decoctions and poultices made from the leaves were commonly prescribed, often used for their cooling and expectorant properties.
Modern Clinical Uses by Herbalists & Naturopaths
Herbalists and naturopaths continue to use loquat leaves and fruits to treat respiratory conditions, like bronchitis and coughs, and to reduce inflammation. Loquat is also promoted for digestive health, immune support, and blood sugar regulation, based on traditional applications and emerging research.
Chemistry & Pharmacology
Loquat contains bioactive compounds such as ursolic acid, beta-amyrin, maslinic acid, and various flavonoids like quercetin and kaempferol. These compounds exhibit antioxidant, anti-inflammatory, and antimicrobial properties, contributing to the herb’s pharmacological effects. Loquat’s triterpenoids have shown promise in promoting liver health, supporting the immune system, and potentially modulating blood sugar levels.
Clinical Trials
Limited clinical trials on humans have been conducted, though animal studies suggest potential benefits in blood sugar regulation, antioxidant activity, and anti-inflammatory effects. More research is needed to substantiate these findings in human populations, particularly in well-designed clinical trials.
Summary
Loquat, rich in bioactive compounds, holds historical and modern promise for respiratory, digestive, and inflammatory conditions. Despite traditional use and promising laboratory studies, more rigorous clinical research is necessary to establish its efficacy and safety comprehensively.

Cautions
Loquat leaves and fruits are generally considered safe when used appropriately, although the seeds contain cyanogenic glycosides, which can release cyanide when ingested in large amounts. Proper preparation can mitigate this risk, as seeds are typically not consumed. Side effects are rare but can include mild gastrointestinal upset.
Avoid large doses. Not for long-term use; contains cyanide-like compounds, but safe to use when following the traditional uses and dose of loquat preparations.
Consulting with a healthcare provider is advisable for guidance, especially in cases of concentrated extracts.
