怎么制作：(找"colloidal silver generator" in amazon.com)
1. Need distilled water, confirm TDS measurement reading 0ppm.
2. Set up as below, the two silver rods shall never touch each other which would create short circut situation.
3. After 2-3 hours, TDS shall read between 1-10 ppm. Unplug the power. In between, you may need to take out the rod and wipe clean some dark colored deposits on rod.
3. 2-3小时后，读数计在 1-10 PPM, 停掉电源。过程中间需要把暗黑色的沉淀物擦掉。
4. filter the liquid with coffee filter.
5. Store it in a jar, avoid light, close lid to store it. Best consume all in 2 weeks.
6. How much to take, it may be different from person to person. I take half a cup every 3 days with 2-3ppm, no issue. There is once I took too much at higher PPM, and my feet felt the chill, but soon it passed with no real issue.
