Just thought I'd say, because nobody else has yet, that the reason that cabbage works is it has a ton of L-Glutamine in it, an amino acid which builds mucal membrane walls.
A note of warning... cabbage juice has a thing called 'goitrogens' in it, which inhibit thyroid hormone (keeps your body from manufacturing it).
"Goitrogens are substances that suppress the function of the thyroid gland by interfering with iodine uptake, which can, as a result, cause an enlargement of the thyroid, i.e., a goiter."
Therefore, whenever you are juicing with cabbage juice you must take L-Tyrosine along with it (and make sure you're taking the proper amount of iodine a day. If you use iodized salt then you are having enough. If you don't? You're probably not.
"The US recommended daily intake of iodine is 150 micrograms (mcg) per day for most adults, and about twice that for pregnant and nursing women."
You should make sure that you take that amount of iodine per day to maintain a healthy thyroid gland.)
Strange enough, too much iodine can also inhibit your thyroid... so if you are taking iodine in more than one source, add them up to make sure you're not taking too much. If you are applying iodine to your body to remove skin cancers (apply 10 times-per-day); then your body will absorb iodine through your skin. So don't supplement if you are doing that.
Your body uses L-Tyrosine to build thyroid hormone... but only if it has enough available iodine (found in seafoods and iodized salt)
You can get L-Tyrosine (and L-Glutamine (you could also take Glutathione),. Taking L-Glutamine will not affect your thyroid) at the Health Food Store.
To make it taste better, try mixing 1/4 carrot juice to 3/4 cabbage juice.
Yes, I have used raw cabbage juice as an enema. An easy way to do it is with an 'enema bulb'. This is the one that I use. You suck up the liquid until it won't take any more, then tip it so the tip is upright and squeeze out the air like when you're topping-off a needle injection. Hold the bulb at the point where the liquid wants to squirt out and then put it back into the cabbage juice and suck in until the entire bulb is filled.
To insert it, put coconut oil on the spout and slowly and carefully slide it in until it is all the way in. Then squish the bulb until you can't squish any more. about a quarter of the bulb's contents will have to be squirted out into the sink afterwards.
To clean the bulb I suck in water, then spit it out, then suck in water, etc. Finally I put a bit of apple cider vinegar in the bulb and swish it around. Let it sit a half-hour, then swish water in and out again.
I have a distiller that heats up, so I place it on top the distiller to dry out. Make sure you dry it out because putting organic material in the bulb and letting it sit around wet might cause black mold to grow inside it (aspergillus) which you certainly wouldn't want to squirt up there.
The next time you use it you should suck water in and out many times just to make sure there is no mildew or fungus inside that might get squirted inside you. It is difficult to completely dry the inside of these closed bulbs.
