Latex allergy stopped me from taking bromelain
I was excited to find a natural solution to inflammation and sinus issues. However, after taking this for less than a week, I had a nosebleed that wouldn't stop. After a deep dive on Google, I found out that if you are allergic to latex, you shouldn't take bromelain. Latex Cross-Reactivity: Bromelain is derived from pineapple. People with a latex allergy are at higher risk of an allergic reaction to bromelain. This allergy can manifest as sneezing, itchy throat, or inflammation in the sinuses, which can trigger nosebleeds. I was taking this to get rid of the inflammation in my sinuses, not add to it. I also had tingling in my fingers, which a deep dive on Google said could happen if I am sensitive to quercetin. Quercetin Side Effects: While generally safe, high-dose or sensitive use of quercetin can cause "tingling in the extremities" (numbness/tingling in hands/feet). Thus is neither a high dose of eother of these, nor was it used long-term, so I guess I am sensitive to them both. Beware if you are sensitive to medications and/or have a latex allergy. I can't say if these pills made a positive impact on me, because I only found negative effects, but that is due to my body being so quirky.
