What the evidence described is related to 岳王庙 in Hangzhou City (杭州市). The four sinners in front of Yue Fei’s (岳飛) tomb are 秦桧/秦檜, 王氏, 张俊/張俊 and 万俟𫧯/万俟卨. ⿰饣善 is a typo here. The current evidence is insufficient for the encoding.

I don’t believe the current evidence is cited from 《中药大辞典》. If 《中药大辞典》 includes this character, please change the evidence.

要素&⿰饣善; means elemental diet, which is also written as 要素膳, 要素饮食, 要素制剂, 要素膳食, 要素型肠内营养制剂 and so on.

Evidence 1 is likely to show a PUA font error where a PUA character for U+2B9EF 𫧯 was intended, but a different font was used to print the book which had ⿰饣善 for that PUA code point.

The new evidence for ⿰饣善 as a derived simplification for 饍 is sufficient, although additional evidence from China would be welcome.
