Abstract :

The primary cause that makes people across the world enter the clinics or emergency departments is pain. Physicians tend to prescribe common pain relievers like opioids or non-steroidal anti-inflammatory medication (NSAIDs). Still, these can be taken in the long term with unpleasant side effects such as bleeding in the gastrointestinal system, kidney damage, and opioids addiction. Due to such risks, patients and doctors are seeking safer alternatives particularly restoratives that are based on nature. Plant extracts normally seem to match that description, as they are more likely to cause milder adverse reactions. We shifted our interest in this research paper to two popular spices, Withania somniferous (also called Ashwagandha) and Piper nigrum (Black Pepper) and we evaluated their analgesic efficacy in Swiss albino mice utilizing the traditional acetic acid writhing test. the actions of each extract separately, observe what would occur when they were combined and determine whether they would be more effective in combination than separately. Mice were given common dosages of methanol extract of Ashwagandha or Black Pepper and aspirin was used as the faithful control. A widely-recognized method of examining pain as it reaches peripheral pathways was the acetic-acid writhing test which documented the number of twisting motions that each group had to experience following the jab. The evidence revealed that all treatments reduced the writhes count by a significant margin, the results of Ashwagandha and Black pepper are the most promising, and it is possible to believe in the proper herbal combination in the future.
