Estimated reading time: 5 minutes

Fructus Gardeniae (Zhi Zi), derived from the fruit of Gardenia jasminoides, has been a staple in traditional medicine systems such as Traditional Medicine and Ayurveda for centuries. Known for its vibrant orange color and potent medicinal properties, this fruit is celebrated for its ability to address various health concerns, from inflammation to liver health (Phatak, 2015).

Fruit is primarily found in regions south of the Yangtze River (China), which is typically harvested in the autumn when it reaches peak maturity. After collection, it is dried to preserve its medicinal properties.

Depending on its intended use, it may be utilized in its crude form or undergo further preparation, such as being stir-baked until brown or carbonized. These preparation methods are believed to modify its therapeutic effects, making it more suitable for specific treatments (Li et al., 2020).
