Er Cha (Catechu) is known for its astringent, anti-inflammatory, and antimicrobial properties. It is used to treat various health conditions, such as mouth and throat infections, digestive problems, skin disorders, and wounds. It is also believed to have blood-activating, hemostatic, and liver-protective effects. In traditional Chinese medicine practice, Er Cha is often used in combination with other herbs to enhance its therapeutic effects and to treat a wide range of health issues. Used topically, Catechu is bitter and astringent, exhibits cool energy, and enters only the Lung meridian. Primarily a damp-draining herb, this substance aids in the generation of flesh and can aid in the arrest of bleeding, especially when caused by heat. It is for these reasons that have been used for athletic injuries. However, it is important to note that the use of Er Cha should be under the guidance of a qualified traditional Chinese medicine practitioner.

Translated literally as "Child's Tea", Catechu appears in the classical Qi Li San Bruise Relieving Powder, and inadvertently in some Wing Chun dit da jow recipes. Er Cha  is typically processed into a powder or extract form, which is then used in various forms of traditional Chinese medicine. In decoction form, catechu is used as a warm, astringent tea to soothe digestive distress and support healthy circulation. When used topically, catechu is believed to help soothe skin irritation and promote the healing of cuts and wounds. As an herbal supplement, catechu is commonly taken in capsule or extract form to support overall health and wellness, and to provide natural relief from digestive discomfort.

High Quality Er Cha: What does it look like?

High quality Er Cha, also known as cutch or catechu, is a dark brown or blackish-brown solid material with a smooth and hard texture. It has a strong, bitter taste and a distinctive earthy aroma. The physical properties of Er Cha can vary depending on the method of preparation, but typically it is sold as a hard, dense, and compact block or lump. The size and shape of the catechu may vary depending on the source, but it is typically cut into thin slices, small pieces, or a fine powder.

When in powder form, Er Cha is a reddish-brown to dark brown, fine to coarse powder made from the heartwood of the Acacia catechu tree. It has a distinctive, astringent taste and is soluble in water. The powder has a slightly sticky consistency, due to its tannin content. The color and aroma of Er Cha Powder can vary based on the processing and storage methods used, but high-quality catechu powder should have a consistent color and aroma, free from any moldy or musty odors.

How is Er Cha prepared and processed?

Catechu, also known as cutch or catechu gum, is native to Southeast Asia, specifically India, Bangladesh, Thailand, and Myanmar. The plant is a member of the legume family and is most commonly found in tropical forests and on the banks of rivers. The plant is a large shrub or small tree that can reach a height of up to 20 meters. The bark is dark brown and rough, and the leaves are pinnate and have a glossy appearance. The plant produces small yellow flowers and pods that contain seeds.

Overall, the Catechu plant grows best in a warm, tropical climate with high humidity.  It prefers well-drained soil with good organic matter content and adequate sunshine. It is very important that the Catechu plant receives high rainfall or access to irrigation as the plant requests consistant moisture. The optimal temperature range between 25-30°C and optimal pH range is between 5.5-7.5

Note: The conditions may vary depending on the specific cultivar and location.

According to traditional Chinese medicine (TCM), Er Cha is usually dried under natural sunlight or with low heat to preserve its natural properties. After drying, it is cut into small pieces or ground into a powder form. The preparation and processing of Er Cha involves soaking it in water or boiling it to extract its essence, which is then used in decoctions, pills, or tinctures. The optimal processing methods vary depending on the specific use of the herb and the condition being treated. It is important to use high quality Er Cha that has been sourced from reputable suppliers to ensure its efficacy and safety.
