Breitbart News reported: In the UK, medicinal plants that are commonly consumed include eufrasias, a medicinal plant that can relieve fever, cough and sore throat.
Eufrasianum, a member of the genus of medicinal plants (genus Eufraca), has been used as a folk remedy in ancient times and was also used as an analgesic in ancient Egypt.
But eufracasia is not widely used today, according to experts.
It is not known whether it can treat a range of conditions including chronic pain, arthritis and cancer.
Eufrasiansae is used as one of the main herbal remedies for coughs, sneezes, asthma and sore throats, according the UK Medicines Regulatory Agency (MRA).
It is also used in some countries as an anti-inflammation, anti-bacterial and anti-viral medicine.
The medicinal value of the plant stems from its ability to relieve congestion and coughs caused by the fungus Clostridium difficile.
However, the herb is also often used in cough and sneezing as a laxative.
A study conducted by the University of Edinburgh in the 1990s found that the herb had no medicinal value, while a survey conducted in 2009 by the Royal Botanic Gardens in London found that eufraisia is also not a good remedy for cough and cough syrup.
“The main medical use of eufresiasae is as a cough and cold reducer, but it is not effective at reducing the symptoms of cough,” said Dr Andrew Bowerman, a specialist in pharmaceuticals and toxicology at the Royal Veterinary College.
The Royal Veterinary Hospital in London has an herbal medicine department, which tests herbal medicines for medicinal value.
In April, the MRA said it was reviewing the use of medicinal eufricae in England, with a view to removing its use from the list of plants considered potentially harmful.
However, there has been no decision on whether the plant will be removed from the UK list.
The MRA has made no move to remove eufreasia from its list, but experts are concerned about the safety of the herb.
There is currently no evidence that euffresiasia can be used to treat arthritis or cancer.
There is also no evidence it can prevent or reduce pain or inflammation caused by Clostrifera, the fungus causing the common cold, and is unlikely to have any medicinal value for cancer patients, said Dr Bowermons.
According to the MDA, eufraniasae can be taken internally or externally and the use in both cases is limited.
While there is no evidence eufriasia can relieve chronic cough or arthritis, it is commonly used to ease coughs.
Although it may not be a good medicine for cancer sufferers, the plant is not likely to be harmful to the elderly and can be eaten in its natural state.
