Excessive Sweating & Body Odour
Increased sweating in cancer patients stems from multiple causes: hormonal therapy-induced hot flashes, cancer fever (tumour fever/B symptoms), certain medications, and the anxiety and autonomic nervous system disruption of treatment. Body odour can change due to altered gut microbiome, metabolic changes, and the compounds excreted in sweat during chemotherapy.

2 Natural Remedies
Clinical-Strength Antiperspirants
Best for: Focal excessive sweating (axillary, palmar), chemotherapy-related sweating
Aluminium chloride-based clinical strength antiperspirants (12–20% aluminium chloride) are significantly more effective than standard products. They work by plugging sweat ducts in treated areas. For patients with excessive axillary (armpit) sweating, they can dramatically reduce moisture and odour.
🧪 How to Prepare
Apply to completely dry skin at bedtime. Cover with plastic wrap for 6–8 hours, then wash off in the morning. Initially use 3–4 nights per week, reducing to once weekly once control is achieved. Suitable for underarms, palms, soles, and groin area.
⏰ When to Take
Nightly application until control is achieved, then as maintenance.
Sage Tea & Sage Supplements
Best for: Hot-flash sweating, hormonal therapy night sweats, general hyperhidrosis
Salvia officinalis (sage) is the most evidence-supported botanical for reducing excessive sweating. Sage contains rosmarinic acid and tannins that reduce sweat gland secretion. Multiple clinical studies show both sage tea and standardised sage leaf tablets significantly reduce hot-flash-associated sweating and general hyperhidrosis.
🧪 How to Prepare
Tea: steep 1 tablespoon fresh sage leaves (or 1 teaspoon dried) in hot (not boiling) water for 10 minutes. Drink 1–2 cups daily, cooled or at room temperature. Supplements: sage leaf extract 300–600 mg standardised tablets twice daily (Salvia efficacy — commercially available product shows good evidence).
⏰ When to Take
Consistently daily — effects build over 2–4 weeks.
