BBC Morning Live’s resident GP Oscar Duke has revealed a bargain 68p kitchen staple that could banish cold and flu symptoms. In an appearance on the show last year, the health expert told presenters Gethin Jones and Helen Skelton how ordinary table salt – available for just 68p at Tesco – can provide ‘instant relief’ without a trip to the chemist.
Most major supermarkets stock table salt for less than £1, including Asda and Waitrose. Dr Duke reminded viewers that whilst there’s no cure for common cold viruses, symptom management remains key.
“Most treatments focus on easing discomfort as the virus runs its course,” he explained. “It is crucial to understand that current remedies do not eliminate the virus but may assist in symptom relief.”
However, he recommended: “Saltwater drops can reduce symptom duration by about two days.”
For homemade saltwater preparation, he recommends mixing three teaspoons of salt with one teaspoon of bicarbonate of soda in cooled boiled water, reports Gloucestershire Live.
“One teaspoon of this mixture can be combined with 250 ml of water, which is about a cup,” he explained. “The solution can be administered using a spray, dropper, or even by sniffing it from the palm to help break down secretions.”
Dr Duke highlighted a recent study that revealed the science behind salt water’s advantages.
The BBC doctor explained: “A recent study conducted in Edinburgh involved around 400 children to investigate the effects of saltwater drops on cold symptoms.
“The study found that using saltwater drops could reduce the duration of symptoms by approximately two days. However, it is important to note that the virus itself is likely still present.
“The saltwater may help clear some of the mucus that contributes to discomfort.”
According to the NHS, cold symptoms develop gradually over two to three days.
The main symptoms include:
- a blocked or runny nose
- sneezing
- a sore throat
- a hoarse voice
- a cough
- feeling tired and unwell
You may also have:
- a high temperature
- aching muscles
- a loss of taste and smell
- a feeling of pressure in your ears and face
Alongside saltwater, Dr Duke suggests honey, which is referenced in national guidelines as a potentially useful treatment for cold symptoms.
A study discovered a night-time dose of honey can ease symptoms; it can also be mixed into hot beverages.
The BBC doctor also states: “Chicken soup has also been the subject of considerable research. Studies suggest it may aid in clearing mucus from the respiratory airways.
“Homemade chicken soup is believed to be more effective than store-bought versions.”
Eating nourishing foods like chicken soup can be one of the most advantageous methods for managing cold symptoms.
