Hello @dianala, Welcome to Connect. I haven't seen any posts on prickly pear cactus (Nopal Cactus) supplements for nerve pain but there may be some who have tried it and hopefully will share what they learned. I don't really think there has been much research done into it's use in supplements form but did find some references if you haven't already seen them:
-- Prickly Pear and Fibromyalgia: A Conceptual Protocol for Plant-Based Symptom Management: https://www.mdpi.com/2072-6643/17/21/3441

"If you have diabetes, you should be particularly careful when consuming nopal cactus or its supplements, as it can affect your blood sugar. Talk to your doctor before taking it, and make sure that you check your blood sugar frequently when testing it."

Are you on any medications for the nerve pain?

@dianala I will now, headed to Moab Utah in a few days - maybe I’ll just pick some fresh too! Thanks for the tip
