Vaginal yeast infections, common in women, are caused by Candida overgrowth, leading to irritation, discharge, and itching. While not an STD, sex can increase risk. Causes include antibiotics, diabetes, weakened immunity, hormones, and pregnancy.

Home remedies include:
- Yogurt: Probiotics restore vaginal bacteria; consume plain Greek yogurt or apply topically.
- Oregano oil: Antifungal; dilute with carrier oil and apply externally.
- Coconut oil: Antifungal; apply pure, organic oil topically.
- Garlic: Antifungal; increase dietary intake, avoid vaginal insertion.
- Tea tree oil: Antimicrobial; dilute with carrier oil or use suppositories; test for sensitivity.
- Boric acid: Antiseptic suppositories; use cautiously, avoid if pregnant or on broken skin.
- Apple cider vinegar: Antifungal; add to bathwater, avoid douching.
- Vitamin C: Boosts immunity; increase intake through diet or supplements.
- Vitamin E: Anti-inflammatory; use suppositories or oils topically.
- Lemongrass oil: Antifungal; dilute and apply topically, or use capsules.
These remedies aim to restore vaginal balance and inhibit fungal growth. Seek medical advice for severe or persistent symptoms.
