This trial is testing whether Chinese herbs can help reduce joint and muscle pain in women with breast cancer who are taking letrozole, a common hormone-blocking medication. Researchers want to understand how the herbs work at a biological level and whether they can ease the painful side effects that some women experience while on this treatment.
Many women taking letrozole for breast cancer develop joint and muscle pain that affects their quality of life. This study aims to see if the medication can safely reduce these side effects and help women stay on their cancer treatment without as much discomfort.

You will take standardized Chinese herbs by mouth twice a day for 1 week. Before and immediately after this week of treatment, you will complete questionnaires about your pain, quality of life, stress, and overall health, and you will have blood samples taken so researchers can measure changes in proteins and other biological markers. The study involves two main time points of data collection and will take place at the study hospital.
