** Thanks for contacting with your health concern 1. The product which you have mentioned is prescribed for psoriatic arthritis [as it has powerful anti-inflammatory properties], and yes turmeric [the ingredient circumin] does cause an allergic rash in some patients, so my advice is to stop turmeric for a couple of days and see whether the rash is clearing or not. PS. do check with a Dermatologist to exclude any other cause of your rash [since the rash has developed after 6 months of taking the drug] 2. Also, do note that turmeric [circumin] do elevate the INR in patients on Warfarin [anticoagulant], so avoid taking it. [avoid taking it with clove, garlic, ginseng, ginkgo] - As it lowers blood sugar [avoid taking it with antidiabetic medications] as may cause dangerous hypoglycemia. 3. As it is a health supplement thus doesn t necessarily comes under FDA approval, thus talk to your family doctor about whether turmeric is safe for you or not, don t take unnecessary risks.
