As the cough and cold season arrives, research suggests that a natural extract from the purple coneflower could help prevent a cold from developing or at least shorten it significantly. Chemist and Natural Health Expert Dr Tim Bond said that echinacea purpurea, also known as purple coneflower, might offer some protection from the common cold.
The European Medicines Agency has confirmed that it can prevent and improve the symptoms of cold more rapidly than placebo when taken early, according to Dr Bond. He emphasised that early action matters, advising that at the first signs of a cold, people should consider how to support their symptoms and keep themselves as comfortable as possible.
Evidence for echinacea
Dr Bond explained that while echinacea is not a guaranteed cold-stopper, the science suggests it could help. A meta-analysis of 14 studies found that echinacea reduced the odds of developing a cold by 58% plus, and for study participants who did develop a cold, it reduced its duration by 1.4 days. A Cochrane review also concluded that echinacea had preventive effects, although more research is needed.
Research by Puressentiel reveals that over a third of Britons have dealt with a cough in the last month, while a similar proportion have battled a cold.
Other natural remedies
Dr Bond also highlighted propolis, a compound produced by bees, as another promising plant-based ingredient. In a randomised controlled trial of 122 adults with mild upper respiratory infections, those using a standardised propolis oral spray recovered from their symptoms around two days earlier than those given a placebo.
When nasal congestion is among the first signs of a cold, saline can help loosen mucus and ease discomfort, Dr Bond noted.
Hydration and home environment
Propolis and echinacea are both found in Puressentiel's Respiratory Decongestant Nasal Spray, alongside essential oils and saline. Dr Bond said the 100% natural formula can help to soften nasal mucosa, soothe irritation and relieve nasal congestion if a blocked nose is one of the first symptoms.
He added that hydration, in the form of water, herbal teas, juicy fruits and vegetables, alongside a balanced diet and plenty of rest and good sleep, can help support the body and immune system to ward off colds and coughs. He also suggested considering the home environment during cough and cold season, noting that plant oils work best in combination. Puressentiel's Purifying Air Spray combines 41 essential oils, including eucalyptus, geranium, lemon and lavender.
A total of 18 studies have shown the spray to be clinically effective against viruses, fungi, bacteria and mould, with research also showing improvements in lung function. It can be used throughout the home, including in the bedroom at bedtime.
Dr Bond concluded that the power of plants is evident, with science showing how helpful these plants can be. When taken at the right time, at the first sign of a sniffle, they could not only prevent a cold from developing but also shorten it significantly.
