Skin
Intertrigo
A skin irritation and rash caused by two skin surfaces rubbing together (groin, breasts, underarms, inner thighs), often complicated by bacterial or yeast infection. Treated by keeping the area clean and dry, dietary improvement, and antifungal herbs.
Also known as: Skin fold rash, Intertriginous dermatitis, Body fold rash, ulcer (definition: open sore in tissue lining)
📝 At a glance
Likely root causes: Friction between two skin surfaces in a warm, moist environment; Bacterial and/or yeast (Candida) overgrowth in the moist area; Excess body weight creating larger, deeper skin folds.
First thing to try: Keep the skin surface clean, dry, and free of friction.
See a doctor if: See a doctor if symptoms are severe, persistent, or worsening, or if you are unsure — natural supports are meant to complement, not replace, professional care.
🔎 Start with the cause
Lasting relief rarely comes from covering a symptom. First find what is feeding the problem, change what you can, and then help the body do what it was designed to do — heal.
Likely root causes
- Friction between two skin surfaces in a warm, moist environment
- Bacterial and/or yeast (Candida) overgrowth in the moist area
- Excess body weight creating larger, deeper skin folds
- Excessive perspiration
- Urinary incontinence (keeping skin persistently moist)
- Diabetes (promotes bacterial and fungal infection)
Change what you can
- Keep the skin surface clean, dry, and free of friction.
- Use only natural, chemical-free soaps and products (from health-food stores).
- Apply starch (cornstarch) to add dryness to the area.
- Never use talcum powder -- it contains ground talc rock which can be carcinogenic.
- Eat garlic products daily and take acidophilus to fight bacteria and yeast.
- Avoid sugar and refined foods -- they nourish the bacteria and yeast causing the problem.
- Avoid sitting in one position too long.
- Wear loose-fitting, all-cotton clothing that does not rub on the skin.
- Apply chamomile teaA warm drink made by steeping herbs in hot water. How to make a tea → compresses -- soothing, antibacterial, and healing.
- Apply aloe vera gelA cool, jelly-like preparation that soothes and moisturizes skin. How to make a gel → topically.
- Use teaA warm drink made by steeping herbs in hot water. How to make a tea → tree oil on the affected area -- speeds healing.

This gentle, low-risk habit is the right place to start for most simple friction rashes in skin folds.
How to do it ▾
Why it works: Removing moisture and friction from skin folds interrupts the cycle that lets bacteria and yeast overgrow and irritate the skin, allowing the area to heal.
- Gently pat the skin fold dry with a clean towel after bathing or sweating, rather than rubbing.
- Use a fan or hair dryer on the cool setting on the area for a minute or two, a few times a day.
- Place a clean, dry piece of soft gauze or cotton between skin folds if they touch.
- Wear loose, breathable cotton clothing rather than tight or synthetic fabric.
ongoing daily habit · several times daily
Caution: If the area develops a foul smell, pus, or increasing pain, it likely has a secondary infection and needs medical evaluation. People with diabetes should watch these areas closely, since they are more prone to complications.
When to get help: See a doctor if the rash spreads outside the skin fold, doesn't improve with good hygiene, or shows signs of infection such as fever, spreading redness, or pus.

A helpful next step to add to basic dry-and-separate care if the rash needs a bit more support.
How to do it ▾
Why it works: Cornstarch absorbs surface moisture while a zinc oxide or petroleum-based barrier cream reduces direct skin-on-skin friction, together lowering the conditions that let irritation and overgrowth continue.
- Make sure the skin fold is clean and completely dry before applying anything.
- Dust a light layer of plain cornstarch onto the dry area to absorb moisture, OR apply a barrier cream -- do not combine both at once, since they can form a paste.
- Reapply after bathing or heavy sweating.
- Reassess after a week; if no improvement, see a doctor.
ongoing until skin clears · 1-2 times daily and after sweating
Caution: Never use talcum powder, since inhaled talc particles have been linked to health concerns -- cornstarch is the safer choice. Stop and see a doctor if the area worsens, develops odor, or shows signs of yeast or bacterial infection.
When to get help: Seek medical care if you notice fever, spreading redness beyond the fold, or a foul odor, which suggest infection needing treatment.

A supportive, longer-term habit best combined with the daily dry-and-separate routine, especially for recurring cases.
How to do it ▾
Why it works: Refined sugar can promote yeast and bacterial overgrowth on the skin and in the gut, so reducing it while adding probiotic foods may help rebalance the skin's microbial environment over time.
- Reduce refined sugar and heavily processed foods in the diet while the rash is active.
- Add a serving of plain yogurt or another probiotic food most days.
- Include fresh garlic in meals a few times weekly.
- Continue basic hygiene and drying measures at the same time, since diet alone won't resolve an active friction rash.
2-4 weeks to notice change · daily
Caution: This is a supportive measure, not a cure for an active secondary infection, which may need prescription antifungal or antibiotic cream. People with diabetes should work with their doctor on blood sugar control as part of this approach, not diet changes alone.
When to get help: See a doctor if the area shows pus, a foul smell, spreading redness, or fever.

“Disease is an effort of nature to free the system from conditions that result from a violation of the laws of health... In case of sickness 1cause should be ascertained, 2go to work intelligently to remove the disease. 3Unhealthful conditions should be changed, 4wrong habits corrected. 5Then nature is to be assisted in her effort 6to expel impurities and 7to re-establish right conditions in the system.”
🌿 Overview
Intertrigo is skin irritation or eruption caused by friction between two skin surfaces in warm, moist folds of the body. Bacteria and yeast overgrow in these areas, starting ulceration. It primarily affects overweight women who perspire heavily, or anyone with urinary incontinence. People with diabetes face a higher risk of secondary infections. It is most common in warm climates and during summer months. The solution centers on keeping the affected areas dry and clean, improving the overall diet, and using antifungal and antibacterial agents.
Intertrigo is a skin irritation that develops where two skin surfaces rub together and trap warmth and moisture — in the groin, under the breasts, in the armpits, and in abdominal folds. The friction and dampness leave the skin red, raw, sore, and sometimes cracked, and the warm moist environment can allow yeast or bacteria to take hold, worsening it.
The natural foundation is to reduce the friction and keep the area cool and dry: gentle cleansing and thorough drying, allowing air to the area, wearing loose breathable fabrics, using a barrier where helpful, and managing weight and sweating where relevant. These measures both heal and prevent it. If the area develops a secondary yeast or bacterial infection — with spreading redness, odor, pus, or worsening soreness — antifungal or antibacterial treatment may be needed, so stubborn or infected-looking intertrigo is worth a doctor's review.
Common signs
- Rash, redness, and skin irritation in body fold areas (groin, under breasts, underarms, inner thighs)
- Raw, moist, sometimes malodorous skin in the affected area
- Itching and burning sensation
- Possible ulceration in advanced cases

🍽️ Eating to help
Food is one of the gentlest medicines — small, steady changes help most.
Nourishing whole-food diet free of sugar and refined food (which feed the bacteria and yeast). Garlic daily. Acidophilus product daily. Eliminate processed food.
⚖️ Good to know
- Diabetics are at elevated risk for secondary bacterial infections in intertrigo areas and should monitor carefully for signs of worsening (increased redness, fever, spreading).
- If there are signs of deeper infection (fever, significant pain, spreading redness), seek medical evaluation.
- Intertrigo that doesn't respond to hygiene measures may indicate underlying diabetes or significant candida overgrowth requiring treatment.
