The freshwater pearl is soft, tender and feminine. Like mother-of-pearl, it provides soothing and well-being; it would have positive effects on decalcification problems. Centuries ago, it was already used to treat dementia and epilepsy, as well as depression. In India it was given multiple benefits, especially against phthisis, ophthalmological problems, hemorrhages ... Hindu medicine still uses it, in powder form, to revive energy, in particular sexual. In the East, it is attributed virtues related to fertility and an aphrodisiac character.
