I have high hopes either urea or urine will work wonders. I'm going to start drinking morning urine (midstream) soon, hoping it would help remove immune complexes deposited in my kidneys (and perhaps liver, knee joints, and in scalp capillaries). The urea in the urine may just be what's needed to clear out these immune complexes. The effects are hypertension, arthritis, and hair loss.
I personally prefer urine as heavy metals was my concern, as the urea sold at Health Natura and at Lifegiving Store both contain lead at levels I find to be too high. It's not just them, as the best urea out there could simply. be what they're selling. But I wouldn't be too concerned if the use of the urea is temporary only, as it would be in both our cases.
I may be wrong, but I seem to trust my urine as a source of urea than coming from the USP grade urea we're able to buy. If there's heavy metals in our food, I even think it accumulates in our body, in our adipose tissues as well as in bone marrows, so it doesn't show up in urine unless we're doing some chelation as well as using binders that will bind to the chelated heavy metals.
Either way, heavy metals or not, what's more important is being able to help clear your cataract condition. The heavy metal issue would be inconsequential since the use of the urea is limited in duration, and your exposure to heavy metals is limited.
Glad that it is already having an effect on you! I hope it will on me as well.
yerrag, I hope it will too! What makes you concerned about lead in the purchased urea though? The HN label says it tests at < .001% heavy metals.
