Herbal pain relief balms are widely used topical formulations for the management of headache, muscular pain, joint stiffness, back pain and mild inflammatory conditions (2,6). The increasing awareness regarding adverse effects associated with long-term use of synthetic analgesics has led to a significant shift toward herbal and natural formulations (2,6). Herbal topical formulations are preferred due to their localized action, rapid onset of relief, improved patient compliance and minimal systemic side effects (2). The present study was undertaken to formulate, prepare and evaluate a herbal pain relief balm using natural active ingredients such as menthol, camphor, eucalyptus oil and peppermint oil (1,7,10). Beeswax and petroleum jelly were selected as base materials due to their excellent compatibility with essential oils and their ability to provide suitable semi-solid consistency, stability and spread ability (11,12,14). The balm was prepared using the double boiler method, a standard pharmaceutical technique that ensures controlled heating and prevents degradation of volatile and heat-sensitive components (11,14). The prepared formulation was evaluated for physical appearance, texture, spread ability, melting behaviour, stability under different storage conditions and skin safety using patch testing (11,12). The results indicated that the prepared balm possessed a smooth semi-solid texture, pleasant medicinal odor and good spread ability (11). Stability studies showed no phase separation, cracking or loss of consistency (12,14). Patch test results confirmed that the formulation was non-irritant and safe for topical application (6,15). Application of the balm produced an immediate cooling sensation followed by noticeable relief from mild pain (1,4,7). The findings of this study demonstrate that an effective, safe and economical herbal pain relief balm can be successfully formulated using simple laboratory techniques, highlighting the potential of herbal topical formulations in pain management (6,11).
