Hulda Clark makes great warning to not use isopropyl alcohol as it is a chemical solvent which the body has difficulty detoxifying. In this case, rubbing alcohol could potentially cause swollen lymph nodes. So, it is advised to use pure grain alcohol or maybe 100 proof vodka for topical medical remedies. Weather this safer alcohol would help swollen lymph, I don't know.
Magnet therapy and/or herbal detoxifier like "Red Clover Combination" would help. A warm washcloth dipped in Epsom Salt would help. A Mama-To-Many charcoal poultice would also help.
