Are obsidian and rosewood bracelets good for health?

Concrete contains sand, and if you put the sand under a microscope, you will find that there are all kinds of gems here, but they are just too small. Since there are all kinds of gemstone materials, they naturally have all kinds of effects, such as attracting peach blossoms, aphrodisiac, whitening, and attracting wealth. . . Wait, wait, etc., so believers please insist on sleeping directly on the concrete floor for a year. I estimate that believers can have peach blossoms, perform three thousand times a night, be handsome enough to shock the world, and be as rich as any country. As for someone who got cold and went to the hospital? Well, it must be that the posture is wrong, the way of belief is wrong, the sand has been adulterated... With so many effects, why do you still end up in the hospital? As for red sandalwood, you can see red sandalwood furniture in many museums and XX’s former residence. Beds, chairs, the original owners of these objects slept and sat on these objects almost every day... You can check their age and experience.
