The Arum problem is a big need for confirmation, a strong need to be yourself. Also a strong sexual need, which is not allowed.
Cannot be herself because she cannot be herself in a sexual way.
The Arums contain a lot of calcium oxalate, so the feeling of not belonging to the family, of being a stranger in their own family, of being an adopted child.
What happens then is that they start to demand a lot of attention. They want more and more. Just like Rheum, which also contains a lot of oxalate. And they want to have love. That is an Oxalicum characteristic. Feeling of being repudiated in her own family, not to be loved.
This in itself also belongs to Stage 16, because this plant also has a disgusting smell. So this is typical for the whole family and it is also part of the idea of not belonging (Oxygenium - and needing attention). The Aronskelk is also part of it and can therefore be connected to funerals (the body is then literally the 'mortal remains' = Oxygenium).
Lung problems also belong to this family of the Arums.
Another characteristic is that they want to protect themselves, but they don't succeed. But most important of all is that they want to be seen because of their lack of attention. A cry-out for "See me, hear me, feel me".
This is confirmed by Ulrich Welte, who tells something about a man who has the same irritation around the nose and allergy. Without Ulrich realizing it, the penny now falls, because this man had a presentation that he explicitly wanted Ulrich to listen to him carefully and to take note of what he said. Almost overwhelming.
In the Monocots there are hardly trees, only flowers. This is a sign of more primitive evolution. The Alismatales are more primitive than the Asparagales and Liliales.
Furthermore, Caladium belongs to this family of Araceae and Ictodes (Pothos) foetida (apparently also stinks).
