I had a call from Golden Retriever rescue about a dog they just acquired who is heartworm positive, about 20 pounds underweight and was azotemic when they first found him. Ultrasound (I did not do) showed "one small kidney and one large kidney with abnormal architecture" per owner. Azotemia has resolved after 2 weeks on K/D diet. They do not feel he is a candidate for conventional heartworm treatment and are interested in alternative options. I have the protocol from Manual of Natural Veterinary Medicine involving Ginger, Wormwood, garlic, thyme, and cinnamon tincture combo. I was also planning on adding Bromelain. Is this tincture combo something I can order from you? If so, can you give me an idea of cost as the Rescue is asking me already. I see potential side effects from wormwood include neurotoxicity. I do not see other specific toxicities other than "not for long term use". I am assuming this treatment protocol qualifies as "long term use". How long would you recommend continuing treatment? Any thoughts or concerns about using this in a dog with potentially compromised renal function (I assume they did a UA but have not seen labs). I cannot find info about how this is metabolized in the resources I have (renal or liver), so not sure how to assess risk for increased toxicity in this patient. Thanks! Erin
