A situation has arisen for which the different virtues of both the unprocessed and processed forms of Rehmannia seem indicated. I do not recall having seen them both used in a formula together. As they have differences, but also considerable constituent overlap, I am wondering how you might approach the dosing if you were to combine them both in a triune? My MM sheets may be dated, but I have 1/6-1/9 for Shu Di Huang and 1/6 for Sheng Di Huang. My initial thought is for a likely combined mixture that would be around 2/9 part total of either a 1:1 mixture or slightly more Sheng Di Huang.
