Traditional and Medicinal Uses
In traditional medicine, ginger has been used for centuries to treat a variety of ailments. It is a key component in Ayurvedic medicine, where it is used to balance bodily energies and improve overall health. In Traditional Chinese Medicine (TCM), ginger is employed to warm the body, improve circulation, and aid in digestion.

Cultivation and Harvesting
Ginger is typically grown in tropical and subtropical climates. It requires a warm, humid environment and well-drained soil.

The rhizomes are harvested once the plant’s leaves start to turn yellow and die back.
Storage and Preservation
Fresh ginger should be stored in a cool, dry place, ideally in the refrigerator, where it can last for several weeks. It can also be frozen to extend its shelf life. Dried ginger, in the form of ground or crystallized ginger, should be kept in an airtight container to maintain its flavor and potency.

While ginger is generally considered safe for most people, excessive consumption may lead to gastrointestinal issues such as heartburn, diarrhea, or stomach upset.
