Upon application, you may experience a warming sensation, which can help soothe muscle soreness and tension. This immediate effect is often attributed to ingredients like camphor, active compounds and the warming herbs infused. You should be able to find comfort within 30 minutes to an hour. In terms of longer-term effects, muscle oil can continue to provide relief and relaxation for several hours after application. However, it's important to note that muscle oil is not a cure-all and may not provide instant or long-lasting relief for all individuals or conditions. Additionally, it's worth considering that the effectiveness of muscle oil can also depend on the severity and nature of the muscle discomfort you are experiencing. For more persistent or severe issues, it may be necessary to consult a healthcare professional for a comprehensive evaluation and appropriate treatment.
