SOURCES 

Sometimes doing a materia medica is very difficult. This was one of those. Information all over the place, trying to find all the pieces I needed, including a photo of the plant. Couldn’t find one that I could use, but found one of the roots. There are also multiple spellings of the common name (Dong Quai appears to be the most used) and synonyms for the botanical names!
