Hawthorn Leaves

Hawthorn Leaves (Crataegus pinnatifida), Shan Zha Ye

Overview:
Hawthorn Leaves, known as Shan Zha Ye in Traditional Chinese Medicine (TCM), are the dried leaves of the hawthorn tree (Crataegus pinnatifida). While hawthorn fruit is widely known for aiding digestion, the leaves are particularly valued for promoting cardiovascular health, improving blood circulation, and supporting healthy lipid metabolism. They are often used as a mild herbal remedy for hypertension, arteriosclerosis, and cholesterol imbalance.

Botanical Characteristics:
Crataegus pinnatifida is a deciduous shrub or small tree native to China, bearing white flowers in spring and bright red fruits in autumn. The leaves are ovate or lobed with serrated edges and are typically harvested in summer or early fall for medicinal use.

Traditional and Modern Uses:

• Improves circulation and heart function: Traditionally used to support heart health and relieve symptoms of chest tightness or palpitations.

• Lowers blood lipids: Often used to manage high cholesterol and improve lipid profiles.

• Supports digestion and metabolism: Enhances digestion, especially of fats, and is sometimes combined with hawthorn fruit for digestive support.

• Reduces blood pressure: Used in herbal formulas aimed at mild hypertension or blood vessel health.

Pharmacological Properties:
Hawthorn leaves are rich in flavonoids, polyphenols, and triterpenes. Research suggests these compounds may help dilate blood vessels, reduce blood pressure, lower LDL cholesterol, and improve coronary blood flow. They also possess antioxidant and anti-inflammatory effects.

Preparation and Dosage:
Hawthorn leaves are typically consumed as a tea, decoction, or extract. They can be used alone or with other herbs in cardiovascular or metabolic support formulas. Dosage should be tailored by a healthcare provider.

Precautions:

• Should be used with caution in patients already taking heart or blood pressure medications.

• Not recommended for individuals with low blood pressure unless supervised.

• Pregnant or breastfeeding women should consult a physician before use.
