If you watch one of his YouTube series videos (it has a dutch name that I would never be able to spell, but it is easy to find), he mentions Chia´s work but points out that Enterovirus was found in 20% of controls too. He suggests that this means that it is unlikely to be the underlying problem in these patients. I think he sees herpes viruses in the same way, but his views on all this might have changed since the videos were made. In general, he tries to treat the underlying problem (be it intracellular bacteria, gut dysbiosis or other immune dysfunction) itself rather than all the secondary problems, but then this is what Chia does with Oxymatrine, as far as I am aware. I have not heard of him prescribing Oxymatrine, but he does prescribe other things to strengthen the immune system in some patients, I believe.
