Mushroom I’m-Yunity used for the treatment of canine hemangiosarcoma | VETgirl Veterinary CE Blog

In today's VETgirl online veterinary continuing education blog, we interview Dr. Dorothy Cimino Brown, Professor of Surgery at University of Pennsylvania on the use of the Coriolus versicolor mushroom, known commonly as the Yunzhi mushroom. This mushroom, which has been used in Chinese medicine for more than 2,000 years, is thought to contain immune-boosting properties from polysaccharopeptide (PSP). The specific product being used is I'm-Yunity, made by Chinese Medicine Holdings LTD (NOTE: This product is manufactured in the USA in adherence to USP c-GMP guidelines). A preliminary University of Pennsylvania pilot study that was released in 2012 evaluated 15 dogs diagnosed with hemangiosarcoma that were treated with 25, 50, or 100 mg/kg/day of I'm-Yunity. While there wasn't a statistically significant difference in survival between the three dosage groups, the median survival time was highest in the 100 mg/kg/day group, at 199 days. As as result, a second clinical trial is currently being conducted to evaluate dogs diagnosed with hemangiosarcoma. This will evaluate dogs treated with I'm-Yunity alone, dogs treated with I'm-Yunity + chemotherapy, or dogs treated with chemotherapy alone.

VETgirl is excited to hear the results, as this devastating, aggressive neoplasia often results in immediate euthanasia in the ER, or even with treatment, only up to 3-6 months with traditional therapy. We eagerly away research results to see if a more holistic, safe, benign treatment option through I'm-Yunity will be beneficial for our patients!

  1. Is there a dosage you could give as a supplement everyday prior to them getting the cancer. Seems there are a lot of dogs getting this cancer.
    My dog died 47 days after she had her spleen removed.
    I just can believe how many dogs are getting this cancer.

    • Hi Esther, I would check with a veterinary oncologist on the dose – currently the studies are looking at 50 mg/kg and 100 mg/kg for dogs. I’m so sorry to hear about your dog. 🙁

  2. Thank you for this update. My dog died suddenly – 3 years ago this week. Hermangiosarcoma was determined in the necropsy – no other issues. I have been following the progress on this study ever since. It is a devastating disease – as all cancer is. The speed was breathtaking – no diagnosis, tumor burst, 24 hours later, gone. I hope there is some therapeutic supplemental dosage recommended. Please continue to post – with the honesty and integrity you always have.

    • Thanks for writing Kristen – as a veterinary specialist, I HATE this cancer, as it’s so sudden. It’s awesome to see preliminary clinical trials for those who may not be able to afford chemotherapy, etc. We’ll keep you posted as the study results come available in a few years!

  3. In that the date on the last message here is over a year ago I assume additional studies were not earth shattering. Could you update us on PennVet’s latest findings.

      • No prescription necessary. It’s now available on Amazon but more expensive than the I’m-Unity site. Either way it’s very expensive. We have used it through our German Shepherds chemo along with Yunnan Baiyao Jiaonang. The latter being to help blood clotting in the event of bleeding.

        Right now we are at 151 days since a tumor burst on her spleen and it was removed. She lost approx 1.5l of blood. The only reason we knew something was wrong was because she looked bloated.

        She is 9 now and although very emaciated she has a ravenous appetite and overall is active when we come home etc.

        Next step is oral medicinal treatment as her chemo treatments are complete. Last X-rays were clear and white blood cell count normal.

        So, quality of life is good. I am thankful that we had adopted another German Shepherd rescue just a few months before so she has company through this.

  4. I have found a product that is just the turkey tail mushroom ingredient and it is a lot cheaper. Any thoughts on this?

  5. Can dogs take this before they are officially diagnosed? Our dog just had its spleen removed today due to 8 nodules. Our vet has recommended this but did not mention if we have to wait for the results of the biopsy or not. I’d prefer to start ASAP if we can.

    • Honestly, the few days to wait is ok. With so many nodules, it’s less likely that it’s neoplastic/cancerous but keep us posted!

  6. Has anyone’s dog had weird behavioral changes on this? Last night he couldn’t calm down and seemed super paranoid.

  7. Hi, Kayci. We’re treating our Golden Retriever’s hemangiosarcoma with Im-Yunity, along with a ketogenic diet, CBD oil, detox support, and a few other supplements. He just began Im-Yunity yesterday, so I don’t know whether that’s to come. Is your dog on anything else, such as prednisone? Keagan panted like crazy and drank so much water, it was nuts. He also looked a bit wild-eyed. His conventional vet reduced the dosage, and he’s a bit better now. I so empathize because it’s difficult to know what is causing the behavioral changes. Is the cancer spreading, or is it the treatment? My heart goes out to you.

  8. Kayci, Yes, my Pomerian/Chihuahua mix acts the same way at times. I felt the same way you did. It appears that at times this can cause mood swings. One day he’s hyper and the next a bit more laidback.

  9. How many milligrams are in one capsule? I just ordered for my dog who has lymphoma. This is her second battle with lymphoma, Im praying this battle is as successful as the first.

  10. Ok I’m the cat person here. 11 yr old Maine Coon. Had apparently a very rare presentation. Hemangiosarcoma in the flank not intraabdominal. Operated. Removed. Grew back to 3x as large in 2 months. Not a candidate for chemo. Life expectancy per Vet was 2-3 months. Treated with Imyunity, Cana (THC/CBD) combo and essential oils. That was October 2017. Tumor shrunk/ disappeared in 3 months. Just celebrated his 12 month survival. Couldn’t make this up.

  11. My baby was recently diagnosed with dermal hemangiosarcoma. It has not spread internally. Is I’m Yunity recommended for dermal hemangiosarcoma as well?

  12. While certainly anecdotal, I thought I’d note our experience using this product. Our 11-year-old male Rhodesian Ridgeback was diagnosed with hemangiosarcoma in May 2018, with the presence of significant spleen enlargement and suspected tumor spots on the lungs, along with heart murmur. At the date of diagnosis, the vet told us to expect a very short life expectancy. We immediately began giving him imyunity, along with CBD drops to mitigate inflammation. We opted against chemo, a splenectomy + chemo, or any other form of invasive treatment, focusing instead on quality of life. Well, he has since had only one “episode” (seizure-like loss of limb control, extreme abdominal distention) in October 2018, but lived through it. He has an outstanding quality of life to date. In fact, if one didn’t know of his condition, they’d think there was nothing at all wrong with him. While I’m not sure that the imyunity supplements have stalled the progression of the disease, as there is no sort of control here, I do strongly suspect that it has prolonged his life significantly. While the capsules are expensive, if you compare them to the cost of chemo or other invasive treatment protocols, and factor in that there are no negative side effects, I’d say it’s worth a try.

    Note: this is an unsolicited and unremunerated comment, though I wouldn’t mind a discount coupon or two!
