Simple Summary

Ashwagandha is an adaptogenic herb that may help reduce fatigue from chemotherapy and has shown promise in lab studies for killing cancer cells and curbing inflammation. One study in breast cancer patients found it improved quality of life during treatment.

Evidence at a glance

Tier 2 · animalBreast cancer (supportive)Lung, colon, prostate (preclinical)

Robust preclinical anticancer mechanisms; limited human data focused on supportive care (fatigue reduction) in breast cancer.

How it may work

Ashwagandha (Withania somnifera) and its key compound withaferin A induce apoptosis in cancer cells via ROS generation, mitochondrial disruption, and p53 activation. It inhibits NF-κB signaling, reducing inflammation and angiogenesis. Preclinical data show cytotoxicity against breast, lung, colon, and other cancers, with immunomodulatory effects enhancing T-cell activity. In humans, it may alleviate chemotherapy-induced fatigue.

Dose: as studied, not a recommendation

These are doses as studied or reported, never a recommendation. The right amount of Ashwagandha depends on you, your other medicines, and your situation; decide it with your oncology team and pharmacist, not from a web page.

Ranges seen in adjunct / practice use: 2–6 g (oral) 2 g TID of root extract; with meals to improve tolerance, Based on breast cancer fatigue trial (PMID 23142798); adjust for standardized withanolide content (typically 2.5-5%)..
