Absolutely! Castor Oil packs are great for many things! I plan on using some packs on my knee and my liver since previous packs on my liver seemed to really improve my feeling of congestion. The first twinge of gallbladder ache and I will be running for my Castor Oil.
Body maintenance can be addicting but hey! it is also a healthy habit and you can enjoy the risks of walking barefoot or living life among others when you are equipped with the knowledge of how to "clean up your act"!
Let me know how your building your zapper goes. I would love to build a zapper which I could use with my pets. I use mine on them some and have had great luck in rehabilitating our mastiff who had gotten so lethargic, he spent more time out of his body than in! After a week of zapping, he was always the first to go when I headed for the door!
