I don't know if I can drink this. Most asthma patients are allergic to dust mites. It is suggested that you use a protective cover for your mother's mattress, which can block the contact between dust mite allergens in the mattress and the human body and help asthma patients. Its waterproof and breathable function can not only protect the hygiene of mattress, but also protect the health of sleepers. I think you can let your mother try.
