Translation:Arukh ha-Shulchan…
“ If the purpose of Charoses is to counteract the damaging substance in Maror how can one not not dip the sandwich [the act is need for protection of his health] ? The truth of the matter is that many later authorities dispute this ruling and rule instead that the sandwich should be dipped in Charoses. This is in fact our custom. His reasoning is not easy to understand, though one could suggest that he is of the opinion that the Matzah itself [mixes in while chewing] and counteracts the damaging substances. ”
