(Appearing through steam) Welcome! Let's flush all toxins with a germanium bath! First-time trial just 3,000 yen!
GermaniumGermani: "Lord Germanium! Your power flushes out toxins, right!?"
Germanium: "...I'm a semiconductor. I gave birth to the transistor at Bell Labs in 1947. I support global communications as an optical fiber window material. I am not bath salts."
Germani: "B-but the negative ions..."
Germanium: "'Negative ions' is not a scientific term. And me dissolving in hot water to be absorbed through skin? Don't insult the stratum corneum's barrier function."
Germani: "But all that sweating means..."
Germanium: "The water is hot. Same result with or without stones. Sweat is 99% water and NaCl. The 'toxins' you speak of don't exist."
"Detox" has no scientific definition. Human detoxification is done by the liver and kidneys. Adding stones to hot water changes nothing.
Real germanium is the great semiconductor that powered humanity's IT revolution. Consuming that name as "bath salts" is an insult to science.
