1. Botanical Description and Traditional Uses

Andrographis, scientifically known as Andrographis paniculata, is a perennial herb belonging to the family Acanthaceae. It is commonly referred to as "King of Bitters" or "Chuan Xin Lian" in Chinese, due to its intensely bitter taste. This plant is native to South and Southeast Asia, particularly in countries like India, China, and Thailand, where it thrives in warm, wet climates and is often found in open fields, along roadsides, and in wastelands.

The botanical description of Andrographis includes its distinctive features such as erect stems that can grow up to 80 cm tall, opposite leaves that are lanceolate to elliptical in shape, and terminal or axillary panicles of small, white to pale yellow flowers. The plant also produces small, slender, and slightly curved capsules containing numerous seeds.

Traditionally, Andrographis has been used in various forms, such as decoctions, powders, and extracts, in Ayurvedic, Chinese, and Thai traditional medicine. It has been valued for its wide range of therapeutic properties, which include:

- Anti-inflammatory and antipyretic effects: Used to reduce fever and alleviate inflammation.
- Immunomodulatory properties: Thought to enhance the body's immune response to infections.
- Antimicrobial activity: Employed to combat bacterial and viral infections.
- Hepatoprotective effects: Utilized to protect the liver from damage and promote its health.
- Antioxidant properties: Recognized for its ability to neutralize free radicals and prevent oxidative stress.

In traditional medicine, the whole plant, including leaves, stems, and roots, has been used for its medicinal properties. However, the most bioactive components are found in the above-ground parts of the plant, particularly in the leaves and stems, which are rich in diterpenoid lactones, flavonoids, and other bioactive compounds.

The use of Andrographis whole plant extract has been passed down through generations, and its popularity has grown due to its potential to address a variety of health concerns. As modern research continues to explore its potential, the traditional uses of Andrographis are being validated and further understood in the context of contemporary healthcare practices.
