VERIFIED! Castor oil does work! I didn't believe it myself then I decided to try it last night. It started to shrink down in a matter of hours. This morning I can no long do a "teeter-toter" motion with it as easily as I could last night.. And it's much less noticeable. I saw posts about tea tree oil working, but thought people that posted those messages had a vested interest... then I saw posts about castor oil working and know that obviously no one has a vested interest with that so gave it a shot. I put castor oil on a large bandaid and went to sleep.. It's amazing how it works. I thought it would only work on the cysts that were soft.. cuz mine is hard and on my scalp.. but it worked anyway.. Another week and I'm sure it'll be gone.. No surgery for me!
