Lepidolite Mica thin slab pieces are our favorite form for making elixirs because of this excellent buffering effect; we of course make our elixirs through the indirect multiple Quartz Cylinder methods described earlier.
We know of DSM Chinese Medicine Doctors who routinely give their patients an elixir of Lepidolite water when they arrive at the clinic.

One practitioner described that you can either spend the first twenty minutes of a one hour session listening to the client vent and ramble before they settle down enough to talk about why they came in, or they can be given the Lepidolite elixir and they will calm right down and the session can begin immediately!

Another interesting insight into Lepidolite: it has been mentioned by Jeffrey Yuen in DSM as one possibility to use to help open the Chong energy channel (connected to the Central Column of energy in the centerline of the human body); this can help balance all the chakras through that method.
