Hello,
I can't tell any specific one right away, and this is not too important for this method:
--- mucus is Dampness energy which is Yin
--- you may apply any strong Yang remedy like blackseed, and it will lyse mucus and any Yin formation like tumour
(cancer also).
I use this one for all Yin conditions, as this is extremely powerful remedy and is a Foundation stone for traditional Muslim medicine, where I took it from.
For example, you can help in case of cystic fibrosis, applying it on the zone for stricken organ.
