Based on the search results, I would recommend the 100% Pure Cold-pressed Hexane Free Premium Castor Oil - 500ML for R269. As the largest size at 500ml for a good price, this will provide you with plenty of castor oil to use for pain relief over an extended period. Castor oil is known to help reduce pain when massaged into the skin as it possesses anti-inflammatory properties. The fact that this oil is cold-pressed and hexane-free means it retains more of the beneficial plant compounds while being less processed. I hope this helps provide effective pain relief for you! Let me know if you need anything else.
