Hi, Sir/Madam Welcome to Healthcare Magic. I understand your concern. The red line on the wounded area probably represents signs of inflammation. It s very important that at this stage you do not allow it to get infected leading to pus formation. Yes, Tee tree oil can used effectively at this stage because of its antiinfective and antioxidant properties. At the same time, application of an allopathic medicine will also hasten up your healing. Injuries with vegetable matter are known to cause fungal infections. I generally treat my patients with topical creams of Terbinafine and Betadine to prevent bacterial and fungal infections. I suggest you to please see a doctor if his views are same and if can he prescribe these drugs for you. Steaming is not necessary at this point of time. Of course, you can drink lots of water approx 3l/day to maintain adequate hydration nad hasten healing. All the above measures are absolutely enough. Post your further queries if any. Thank you.
