| How it's made | West-coast sea salt is packed into thick bamboo stems, sealed with yellow clay, and roasted in a pine-wood fire at about 800 °C for 12–14 hours. The salt is ground, repacked and roasted again, up to nine times; the final firing above 1,000 °C melts it. |
| Colour and texture | Grey to dark, with blue, yellow, red, white and black crystals; the most prized is “purple bamboo salt.” |

| Health claims | It is used in Korean folk medicine, but it is still 85–98% sodium chloride. |
The story
Bamboo salt was traditionally roasted two or three times; the nine-times method was developed in the 20th century. The bamboo burns away during roasting, leaving a column of salt that has picked up a distinctive flavour Koreans call gamrojung.

These health claims appear on packaging and in wellness media. We include them so you can recognise them; none is supported by good evidence.
