Integrating Traditional East Asian Medicine Dietary and Herbal Therapies for Supporting Cancer Treatment and Survivorship in the West

Traditional East Asian Medicine (TEAM) dietary and herbal therapies emphasize balance, nourishment, and resilience, and have long supported cancer care in Asia. In Western integrative oncology, these therapies are increasingly being used to manage side effects, enhance quality of life, and support survivorship. This retrospective study included patients to illustrate the integration of TEAM therapies in Western academic settings. Case 1, was an 84-year-old woman with Stage 4 bladder and kidney cancer who discontinued immunotherapy due to the side effects of treatment (dietary and herbal). A TEAM-informed dietary and herbal formulas plan was implemented alongside integrative group visits. Case 2, was a 65-year-old woman with metastatic breast cancer experiencing endocrine therapy-related insomnia. She was treated with Suan Zao Ren Tang and a comprehensive sleep support plan (dietary, herbal, and cancer-related medications - i.e letrozole, abemaciclib, and zoledronic acid). In Case 1, the patient gained 3.2 kg, her foot ulcers healed, sleep and mobility improved, and she transitioned from using a wheelchair to using walker. In Case 2, the patient reported improved sleep within weeks of using Suan Zao Ren Tang, she discontinued use after 4 months, and 2 months later, she had maintained restful sleep without recurrence of insomnia. Both patients experienced enhanced quality of life, and treatment adherence without adverse effects. These cases highlight the potential of personalized, culturally sensitive TEAM dietary and herbal therapies to support symptom management and survivorship in cancer care. Integrative approaches combining traditional and modern modalities can improve patient outcomes and quality of life, even in advanced stages of disease.
