Bacterial Blood Leeching
While the idea of leeching is frowned upon in the modern and magical worlds, using Sapient Filtering Agar is the only known cure for Bacterial Ki Blockage.
The extraction is risky for the practitioner, because the patient may be at the point they will attack any being with a sigificant amount of ki. Additionally, it's time consuming. The patient must be restrained and sedated. A set of 3 grapefruit or larger sized sapient agar needs to be gathered. One at a time, each agar needs to press a thin film of itself into a large cut in a major artery of the patient. From there, the agar will seal off the wound and filter the blood by rotating the section of itself that acts as the filter. The agar filters the entirety of the patient's blood this way, taking it in and only absorbing the harmful bacteria and gaining the magic the pathogens stole in return for their service. The agar can be given a sample to learn what to filter. But they have a natural affinity for pathogens that attack magic. No need to prime them for this disease. The process can take 1-2 days because the bacteria rapidly multiply in the patient's body while the agar is filtering.
