Cold sores are caused by the herpes simplex virus (HSV-1). HSV-1 is typically contracted in early childhood, with an estimated 90% of all adults being exposed to this virus at some point in their lives.
Studies suggest that the herpes simplex virus may require the amino acid arginine for replication, while lysine can help counteract this effect. Arginine-rich foods include chocolate, nuts, oats, carob, coconut, and soybeans, which can trigger outbreaks in some. Lysine is present in vegetables, legumes, fish, sprouts, and dairy products. For some individuals, lysine supplements may help reduce the frequency or severity of outbreaks.
Vitamin C and zinc can be taken internally and applied topically to manage cold sores. You will need to take approximately 50mg of zinc daily and up to 5,000mg of vitamin C in 1,000mg increments throughout the day for three days, then reduce this to 3,000mg for maintenance.
Zinc has been shown to be effective in inhibiting HSV replication in research studies. It is also well-documented for immune support, and specifically in the management of viral infections.
Vitamin C is known as an immune-supportive nutrient, and it also specifically works against the herpes virus (this applies to other herpes-related conditions such as shingles, genital herpes, and the Epstein-Barr virus). Vitamin D is another crucial nutrient for immune support, and individuals dealing with recurrent cold sores may have lower levels of it in their blood.
One of the most effective topical treatments is a concentrated extract of lemon balm (Melissa officinalis) applied to the affected area. Lemon balm contains several constituents that work synergistically to prevent the virus from taking hold, and is most effective when used as a cream or balm. The recommended extract strength is 70:1 to arrest the outbreak and promote rapid healing of the blisters.
If you are unable to track down this concentrated lemon balm extract, consider the more widely available option, propolis extract. Topically, propolis, which bees collect from resins, gums, and sticky plant buds, can help heal lesions quickly and reduce the likelihood of additional infection. Check out the Cork business Hanna’s Bees (hannasbees.ie) for a wide range of bee products, including propolis tincture at only €14.50 for 20ml (which is an excellent size for travel and will last an age).
We’re taking the ferry to travel to France for our summer holidays. I’ve three children under 10, and all of them get travel sickness. What remedy would you recommend?
Two excellent herbal remedies for motion or travel sickness are chamomile and ginger. You can combine these herbs and add honey to sweeten if needed. Use a teaspoon of dried herbs per cup of boiling water and steep for four to six minutes. This infusion doesn’t have to be taken hot — you can strain it off and let it cool, then store it in a water bottle.
Additionally, consider packing Sea Bands, which are designed to be worn over the acupressure points in the wrist, allowing you to manage any symptoms as soon as nausea arises. It is a good idea to practise using the bands in advance of the holidays. Ask your children to wear the bands on both wrists for around 10-15 minutes before they hop in the car. These are relatively inexpensive and can be found at most pharmacies.
