. He described the wood as white in color. It was prepared by being sliced into very thin chips. The chips were then placed in clear spring water. After about half an hour, the water starts to turn a very pale blue, turning bluer as time passes. The water is then drunk neat or mixed with wine. He observed that despite the change in color, the wood itself imparts no taste to the water.

handspan in diameter, about , and adorned with variegated lines. Shavings from the same wood were included with the cup. Bauhin observed that when water was poured into the cup with the wood shavings, the water shortly turned into "a wonderful blue and yellow color, and when held up against the light beautifully resembled the varying color of the opal, giving forth reflections, as in that gem, of fiery yellow, bright red, glowing purple, and sea green most wonderful to behold." Bauhin believed that the wood was taken from a species of ash (''
