The harms of cassia seed pillows
The potential harms of cassia seed pillows commonly include allergies, headaches, and dysmenorrhea. A detailed analysis is as follows:
1. Allergies
Cassia seeds are mature seeds of Cassia obtusifolia, with a bitter, salty, and sweet taste and a cold nature. If not thoroughly cleaned before being used to make pillows, they may contain impurities that can irritate the respiratory tract, eyes, and other tissues, leading to allergic symptoms such as sneezing, runny nose, and itchy eyes.
2. Headaches
Due to their cold nature, long-term use of cassia seed pillows may allow coldness to invade the head, impairing blood circulation and potentially causing headaches or a feeling of head fullness.
3. Dysmenorrhea
The cold nature of cassia seeds may spread from the head throughout the body. When it affects the uterus, it may easily lead to cold uterus (gonghan), resulting in dysmenorrhea and poor menstrual flow.
In addition, cassia seed pillows may also contribute to spleen and stomach deficiency-cold. Individuals with weak constitutions should avoid frequent contact with substances of cold nature. If any health issues arise, prompt medical attention and appropriate treatment are recommended.
