·     Tea Tree (Melaleuca alternifolia)

• Key Compounds: Terpinen-4-ol, α-terpineol
• Mechanism:
  • Disrupts viral membranes and capsid proteins.
  • Penetrates hyperkeratotic tissue to break down infected cells.
  • Prevents bacterial superinfection in cracked or thickened wart skin.

·     Oregano (Origanum vulgare)

• Key Compounds: Carvacrol, Thymol
• Mechanism:
  • Induces cytotoxicity in abnormal keratinocytes.
  • Powerful antiviral action, especially against DNA viruses like HPV.
  • Immune stimulant at the site of application (increased local white cell activity).

·     Lemongrass (Cymbopogon citratus)

• Key Compounds: Citral, Geranial
• Mechanism:
  • Acts as a surface astringent and drying agent.
  • Antiviral and keratolytic — accelerates the sloughing off, of thick wart tissue.
  • Promotes epidermal detoxification.

·     Thyme (Thymus vulgaris)

• Key Compounds: Thymol, Carvacrol
• Mechanism:
  • Suppresses HPV replication within epidermal tissue.
  • Boosts local T-cell mediated immune activity.
  • Reduces inflammation at lesion margins.

·     Frankincense (Boswellia carterii)

• Key Compounds: Boswellic acids, α-pinene
• Mechanism:
  • Inhibits 5-lipoxygenase activity to reduce chronic inflammation.
  • Stimulates dermal fibroblasts and wound closure post-lesion.
  • Minimizes scar formation after tissue resolution.

·     Myrrh (Commiphora myrrha)

• Key Compounds: Furanoeudesma-1,3-diene, Curzerene
• Mechanism:
  • Acts as an immune modulator and antimicrobial.
  • Supports tissue granulation and healing after wart resolution.
  • Reduces local irritation caused by tissue breakdown.

Carrier Oils:

MCT Oil

• Enhances transdermal absorption of volatile active compounds.
• Non-comedogenic and rapidly absorbed into dermal tissue.

Grapeseed Oil

• Rich in linoleic acid and antioxidants, supports skin repair and prevents excessive drying.
• Provides a stable base for dermal delivery of keratolytic oils.
