| Finasteride | Caution | Saw palmetto (Serenoa repens) has antiandrogenic and 5-alpha-reductase-related activity, overlapping with finasteride therapy for BPH or... |
| Pueraria Mirifica | Caution | Both are used for hormone-related goals and may complicate assessment of breast, menstrual, prostate, or endocrine symptoms. |
| Testosterone | Caution | Saw palmetto is often marketed for androgen and prostate symptoms, but clinically meaningful hormone-lowering or BPH symptom benefit is not well... details → |
| Warfarin | Caution | Saw palmetto has been linked to coagulopathy and excessive surgical bleeding in case reports, including hematuria and intraoperative hemorrhage.... |
| Wild Yam | Caution | Both are marketed for hormone-related goals, but wild yam has weak evidence and the combination may encourage unsupervised endocrine self-treatment. |
| Beta-Sitosterol | Synergy | Both are common in BPH formulas and may provide complementary urinary symptom support. |
| Fish Oil | Synergy | Both support prostate health through complementary mechanisms; combined use is common in men's BPH protocols. |
