    I would really love to leave a review on how fabulous I think your products are. Long story short I had sepsis 2 years ago caused by a simple water infection, turned to a kidney infection and ended up nearly dying with sepsis. It damaged my kidneys, scarred my lungs but worst of all for me was IC. I’m 36 and it has ruled me for 2 years. I’ve had surgery 3 times and only just been taken off antibiotics for it all but 6 months ago after my last lot of bladder surgery my urologist came to one if you’re talks in England and put me on the super strength aloe Vera and it seemed to help but wasn’t perfect. But after ordering my last batch I came across your blog for Quercetin and thought what the hell. I’ve got to the point where I actually get a bit desperate because I don’t want to be ruled by it anymore and I’m not kidding I took 1 capsule in the morning with a super strength aloe vera and within an hour I felt completely normal?! I haven’t felt like that for 2 years. I also slept solid for 8 hours and didn’t get up once for a wee stop. I was getting up at least 4 times every night and my kidney pain is non existent at the moment. I took my first capsule 2 days ago and I only take one in the morning and one at night and I am gob smacked at the difference it has made to me. All I can say is thank you.

    Your products have changed my life virtually overnight and I wanted to share my story with you.

    A little over 3 years ago I thought I had a urinary tract infection. Long story short, I ended up being diagnosed with Interstitial Cystitis and I was just 37. It has been a rough 3 years for me. I love spicy foods and I really love coffee and I pretty much had to give it all up. I spent lots of time researching products that could maybe help me. Eventually, I found Desert Harvest. I first ordered the Aloe Vera a few months ago but I didn’t realize there was a regimen for people with IC. So, I did one in the morning and one at night and it didn’t really help. (Here comes the really exciting part…)

    I was cleaning my desk area a little over a week ago and I found your catalog and was flipping through it. That’s when I saw your recommended dosing for IC. I quickly ordered a new bottle so I could give it another try. Before it arrived, I took an over the counter UTI test. It showed me being dark purple which indicates white blood cells/inflammation, but negative for bacterial (that’s generally how it works for IC). I immediately started the Aloe Vera Capsules 3 in the morning and 3 in the evening. I could definitely tell a huge difference. Then, I received THE EMAIL from you about bladder awareness month and an IC Starter Kit. I was like, “what is that – there’s more?” I read about the Quercetin and it said something about how people with IC have twice as much histamine in their bladders. That’s when everything came full circle for me. When I was 18, I was diagnosed with chronic hives and took Claritin (an anti-histamine) until about 3 years ago. My hives had stopped and I thought why am I taking this? I think stopping the Claritin must have really impacted my bladder. I received the Quercetin last Saturday and took one dose that afternoon. I could not believe the results. I mean it was like I had my bladder back. In fact, I took another UTI test that night and can you believe that the Leukocytes came back negative?! Totally clear! I had only been taking the Aloe Vera Capsules for a few days and only 1 dosage of the Quercetin.

    It has now been a week and my bladder feels completely back to normal. I can’t even tell you how incredibly thankful I am for your company and your products! What you are doing is life changing for people like me. I wish I could hug all of you!
