How Helichrysum Essential Oil Aids Wound Healing in Radiation Therapy Patients

Helichrysum essential oil (Helichrysum italicum), extracted from the helichrysum plant, is commonly used in aromatherapy. It contains active compounds such as nerol acetate and italidiones, possessing anti-inflammatory, antibacterial, antioxidant, and tissue-regenerating properties. Radiation therapy often causes skin damage, such as radiation dermatitis, presenting as redness, ulcers, and delayed healing. Helichrysum essential oil may assist wound healing through the following mechanisms:

• Anti-inflammatory Effects: Reduces the release of inflammatory factors, alleviating redness, pain, and itching, thereby improving patient comfort.
• Antibacterial Effects: Inhibits bacterial growth (e.g., Staphylococcus aureus), preventing wound infection and reducing complication risks in immunocompromised patients post-radiation.
• Promotion of Cell Regeneration: Stimulates the proliferation of fibroblasts and keratinocytes, accelerating wound closure and tissue repair.
• Antioxidant Effects: Neutralizes free radicals, mitigating oxidative stress damage (which is increased by radiation therapy), and protects the skin barrier.
• Aromatherapy Benefits: Inhaling the vapor can alleviate anxiety and stress, indirectly boosting immune function and healing speed (via nervous system modulation).

Usage Recommendations:

• Topical Application (Diluted): Mix 1-2 drops of helichrysum essential oil with 10ml of carrier oil (e.g., coconut or jojoba oil). Gently apply to the skin around the wound (avoid direct contact with open wounds).
• Aromatic Inhalation: Use in a diffuser, 1-2 times daily for 10-15 minutes per session, to aid relaxation.

Precautions:

• Consult a Doctor or Professional Aromatherapist: Ensure compatibility with the radiation treatment plan and avoid interference with therapy.
• Skin Patch Test: Perform a test on a small skin area before first use to check for allergic reactions.
• Limited Scientific Evidence: Use as a complementary therapy; it does not replace medical care. Severe wounds require professional treatment.
• Avoid Internal Use: For external or aromatic use only. Use with caution in pregnant women and children.
