(Red Herbs) In raw medicine, "Chicon (Purple root)" is called "Cardinal (Red Period)". As its name suggests, it is a plant with colors of "red" and "purple". The same perennial plant as purple roots, has been used in various medications and is also used as dyes. In the Edo period, there was a habit of being able to use as a live medicine, and wrapping the fabric that was dyed to the sickness of the disease, wishing to healing the disease. However, it seems to be more difficult than a regular plant dye, and therefore purple has become a noble color. Color samples shown are from alcohol extracts. Please refer to the posted color samples. At 3.5 oz (100 g) you can dye one T-shirt or one large scarf (consistency and color may vary depending on the material and dye). About the plant dyes we use at our shop to produce plant dyes that are originally sold as biological drugs, and are grown by our "dyeing farm", which is used for all plants in dyes and weaves. They do not use pesticides or chemical fertilizers as much as possible. Therefore, we take great care of our products, but in rare cases there may be some insects inside. Please note that there is no quality issue with the dye. Make your work safe and natural. We got you covered!
