Quick information

1. Origin and description

Forsythia Fruit is the dried fruit of the Forsythia plant, a shrub in the Oleaceae family that commonly grows in temperate climates. The plant has long arching branches, opposite leaves and bright yellow flowers that bloom early in spring. After the flowers fade, the plant produces elongated oval fruits that dry with age and split into two sections.

This herb is usually harvested at two different stages. The nearly ripe green fruit is steamed or briefly boiled, then dried, and is commonly known as Qing Qiao. The fully ripe fruit is dried naturally and usually contains seeds inside; it is often called Lao Qiao. Both types are used medicinally, but their traditional applications may have different emphases.

The dried herb is greenish brown or yellowish brown, with a wrinkled outer shell, pointed tip and a hollow interior or small seeds inside. Good-quality Forsythia Fruit should be evenly dried, lightly aromatic, bitter in taste, and free from moisture or mold.

In some references, Forsythia Fruit is also recorded as Forsythia suspensa. When buying the herb, it is important to distinguish it from similar dried fruits, because using the wrong ingredient may change the direction and effect of a herbal formula.

3. Nature, taste and meridian entry

According to TCM, Forsythia Fruit has a bitter taste and a slightly cold nature. Its bitter taste helps clear and drain heat, while its slightly cold nature supports cooling, especially when there are signs of heat-toxin, swelling, red throat or boils.

This herb is commonly associated with the Lung, Heart and Small Intestine meridians. Through the Lung meridian, it helps release wind-heat and support early-stage feverish colds, sore throat and mild cough related to heat. Through the Heart meridian, it helps clear heat and ease irritability. Through the Small Intestine meridian, it helps guide heat downward.

4. Benefits of Forsythia Fruit in TCM

Forsythia Fruit is a representative herb in the category of clearing heat and resolving toxicity. Its main traditional benefits include:

• Clearing heat and resolving toxicity in heat-toxin patterns.
