Specific strain varieties for ohn ingredients
So a couple weeks ago I started my ohn, I sourced all the ingredients locally and didn’t think much of the specific varieties of each, specifically the dry ones, I got Angelica, licorice root and cinnamon but upon listening to one of drakes lesson videos I heard him say that they were specifications for strain. After that I oooked into it and found the variety names, none of the ingredients I purchased were the exact strain of each plant.... I am just wondering how imperative those details are to the all around effectivness of my ohn
The answer
In practice the Angelicas are almost identical in effect. The cinnamon and licorice will have slightly different properties, but will still be effective as the idea of OHN is KNF Medicine primarily focused on digestion and supporting female reproduction.

The book names species for the three dry herbs: gigantic angelica root (Angelica gigans), cinnamon bark and licorice root (Glycyrrhiza glabra). (Cho, Recipe, p. 24)
The library describes OHN as a mix of herbs with a common function, aiding digestion and fighting pathogens. It is not a fixed ingredient list. (Office Hours Jan 2026, 24:21)
When you cannot match the book, Drake says to follow the book while gradually testing local substitutes. (Office Hours Ep. 15, 50:27)
Check the form of what you bought. Powders are too hard to sieve and turn into sludge, so use chipped or fresh bark instead. (Office Hours Ep. 11, 50:35)
The library does not say how much a species swap changes the result.
