If Xingyue Bodhi comes into contact with water or human sweat, the red substance remaining in its "star" will be dissolved, so the surface of Bodhi will be dyed red, resulting in the phenomenon that Bodhi turns red.
It's best not to get wet with the newly bought Xingyue Bodhi, and just play with your hands. You should wipe it with gloves or bath towel for a while, and then use the hand plate to avoid the phenomenon of bodhi red.
Extended data:
The stars and the moon are seeds, not fruits.
Xingyue Bodhi is the seed of the tropical plant Huangteng. The prototype of the seed is gray and irregular, like a small ingot.
All kinds of regularly shaped bodhis seen in the market are post-processed products. Now we often say that there are even black spots on the surface of beads with a concave circle in the middle, which looks like stars holding the moon, forming a trend that stars hold the moon, so it is named Xingyue Bodhi. Known as one of the "four famous pearls" of Bodhi.
