Free Sample Isatis Leaf Extract Isatis Tinctoria Extract with High Quality
Product Description
Introduction:
Isatis Tinctoria Extract is derived from the roots and leaves of Isatis tinctoria, commonly known as woad, a plant with deep historical roots in traditional Chinese and European medicine. This potent extract contains bioactive compounds such as indirubin, indigo, and isatan B, which contribute to its antiviral, anti-inflammatory, and immunomodulatory properties. Celebrated for centuries as a natural remedy for infections and inflammatory conditions, modern research has validated its efficacy against respiratory viruses and immune-related disorders. The extract is typically obtained through ethanol or water extraction methods to concentrate its active alkaloids and flavonoids, yielding a blue-green powder that embodies both ancient therapeutic wisdom and contemporary scientific validation.

Applications of Isatis Tinctoria Extract
Isatis Tinctoria Extract is widely used in immune support formulations, particularly for respiratory health, where its antiviral compounds help combat colds, flu, and other viral infections. Its anti-inflammatory effects make it valuable in throat lozenges and sinus relief products. The extract is also incorporated into dermatological creams and ointments for conditions like psoriasis and eczema, thanks to its ability to soothe irritation and reduce redness. Emerging research explores its potential in oncology due to indirubin's ability to inhibit abnormal cell proliferation. In functional beverages, it adds both bioactive benefits and a natural pigment. With growing interest in plant-based antivirals, Isatis Tinctoria Extract is gaining global recognition, while sustainable cultivation practices ensure the preservation of this historically significant botanical.
