It worked for me also,
had a cyst on my chest develop and was quite upset because I'm 32, and would think I'd stop getting these by now.
anyway, I let it soak in castor oil over night, and the next morning I was able to expel everything, including a decent sized plug that had been pretty deep. Every time this happened before, by 2 days, the cysts was back. This time I kept it covered by a bandage soaked in castor oil, and it didn't come back. In 14 years of getting these things, this has never happened so fast, and I've expelled the goo from these cysts what feels likes hundreds of times.
