Using crystal elixirs are super beneficial. Crystals are not all created equal. Even though there are many benefits to working with gems and minerals, some are not safe to injest. Especially in elixirs.
If you are new to elixirs, there are two methods: direct and indirect method.
The direct method is simply a crystal added directly to your water. Amethyst, Rose Quartz, Smoky Quarts, Clear Quartz are great crystals to use in elixir direct method.
The indirect method is simply setting your glass of water in a larger bowl. Add any of the crystals into the dry bowl surrounding your water container and let it charge.
Note: using tumbled or polished stones is recommended for direct method for safety reasons from chipping or breaking and accidentally ingesting.
