Qing Dai, also known as indigo naturalis, is a blue-black powder derived from the leaves and stems of plants such as Indigofera tinctoria and Strobilanthes cusia. This therapeutic compound has been used in Chinese medicine for generations and is known for its striking blue color, which is how it got its name, 'Indigo'.
The active components of indigo naturalis include indigo, indirubin, and tryptanthrin. These compounds are believed to have anti-inflammatory and immune-regulatory effects, which may help reduce the symptoms and progression of certain autoimmune diseases.
Qing Dai powder is generally taken in doses of 1-2 grams daily. However, always follow your healthcare provider's instructions, as the dosage can vary based on your condition and response to treatment.
Qing Dai may be taken in capsule form or loose powder. Powders may be mixed with warm water or tea.
Qing Dai typically starts to show effects within one to two weeks of consistent use. However, like all treatments, its efficacy can vary from person to person.
While Qing Dai is generally considered safe for most people, it can cause side effects in some individuals, including headaches and abdominal pain. Women who are pregnant or nursing, as well as people with liver disease, should avoid or use indigo with caution.
As with any Chinese herb, we recommend consulting with a qualified practitioner of traditional Chinese medicine (TCM) about Qing Dai before any course of treatment is started.
For practitioners, Treasure of the East offers full-spectrum Qing Dai powder and capsules. We also offer bulk Qing Dai, offering a savings of 20% compared to the same herbs in bottles!
If you’re a consumer looking to purchase indigo powder, look for suppliers who provide clear information about the product's origin, purity, and testing procedures to ensure you're getting a high-quality product.
