Chinese people have had the habit of using the residue of Chinese Herbs to soak feet to alleviate diseases since ancient times. Nowadays, the residue from which active ingredients were extracted is often discarded in the production process of Chinese patent medicine. In this design, the residue of Chinese Herbs is pressed into pharmaceutical packaging for recycling. After taking the medicine, the packaging made of Chinese medicine residue can be used to soak feet, achieving the effect of relieving the discomfort and getting to zero emissions.
