What a cutie
I will say when I asked Sabine about a diet for PLE she had some recommendations right away. One of those was using coconut oil, something about that type of oil stimulating moving through the lymphs.
The circulatory systems and blood vessels might be done through some key supplements. Off the top of my head, I would look into vit C, rutin, etc.
Vitamin B12 is very important for stagnant lymph nodes.
