1. Origin and description

Star Anise is the dried ripe fruit of Illicium verum, an evergreen tree traditionally classified in the Illiciaceae family. The tree generally grows 6–10 meters tall, with thick dark-green leaves and small pale flowers. Its fruit has a distinctive star shape, usually consisting of six to eight pointed segments, with each segment containing a small seed.

The plant is widely cultivated in northern mountainous areas of Vietnam, particularly Lang Son and Cao Bang, as well as in southern China. The fruits are generally harvested before full maturity and then sun-dried or gently dried until they become reddish to dark brown and develop their characteristic strong aroma.

Good-quality medicinal material should have thick, intact segments, a naturally strong fragrance, and no signs of mold, excessive moisture, or unusual odor.

In TCM, the herb is valued both as a medicinal ingredient and as an aromatic spice, especially for its traditional ability to warm the interior and regulate digestive function.

2. Related names of Star Anise

Other names: Đại hồi, Hồi hương, Bát giác hồi, Đại hồi hương, Hoa hồi, Tai vị, Chinese star anise, star anise fruit, eight-pointed anise.

Scientific name: Illicium verum Hook.f.

Pinyin name: Da Hui Xiang or Ba Jiao.

Chinese name: 大茴香 or 八角.

The characteristic star-shaped fruit makes this herb easy to recognize. However, medicinal and culinary material should come from properly identified Illicium verum and a reliable source, as other visually similar species should not automatically be considered suitable for consumption.

3. Flavors, Nature – Meridian

According to TCM theory, this herb is Pungent in flavor, Warm in nature, and enters the Spleen, Stomach, and Kidney Meridians.

The Pungent flavor is traditionally associated with promoting Qi movement and dispersing Cold. Its Warm nature helps warm the Spleen and Stomach, making it suitable for selected patterns involving abdominal Cold, digestive weakness, cramping, or discomfort after consuming cold foods.

Its Kidney Meridian affinity is traditionally associated with warming Kidney Yang and supporting Cold-related discomfort in the lower abdomen or lower back. For this reason, the herb often appears in formulas for internal Cold patterns.

4. Benefits of Star Anise in TCM

• Warms the Spleen and Stomach: Traditionally used to ease abdominal Cold, bloating, fullness, and poor digestion related to Cold patterns.
• Supports relief of Cold-related pain: May help with abdominal cramping, lower abdominal discomfort, or stomach discomfort when Cold is considered a contributing factor.
• Moves Qi and disperses Cold: Traditionally used to improve Qi circulation and reduce sensations of tightness or cramping.
• Supports digestion: Its aromatic nature may help stimulate appetite and reduce digestive heaviness or discomfort.
• Used as an aromatic culinary herb: Frequently added to soups, broths, stews, and medicinal foods for flavor and warming support.

Modern research has identified aromatic compounds such as anethole in Illicium verum. These constituents have been studied for antimicrobial, digestive, and smooth-muscle-related effects. Traditional uses, however, should not replace medical care for persistent abdominal pain, vomiting, fever, or other significant digestive symptoms.

5. How to use and dosage

A commonly referenced medicinal dosage is 3–6 g per day. The appropriate amount may vary according to constitution, preparation method, and the other herbs in a formula.
