Thank you, Lapis, for your prompt reply and feedback!

I'm not familiar with either of these....
--> May I assume the malic acid is available in capsules? If so, what kind of dosage would be appropriate?
--> As for the gold coin grass, is it taken orally or brewed as a tea?

Also:
--> Are both of these items readily available in health food stores, or do I need to find a speciality supplier?
--> How long should I use these before initiating the flush?
--> Could one/both of these help to soften any stones that might be causing biliary colic/congestion (tightness near the rib cage)?

With appreciation,
Metta
