REUTERS/Jason Reed PHOENIX (Reuters) – An edible oil that contains rosemary may not have been the intended source of a new batch of potentially harmful chemicals in a topical treatment for psoriasis, the Food and Drug Administration said on Wednesday.
Rosemary oil is one of several edible oils, including mint oil, that contain the ingredient rosemary.
It was found to be present in a batch of topical products marketed to treat psorias psorifera and was approved for use in a number of topical treatments, including the topical cream and gel for psoriatic arthritis, the FDA said.
The agency did not identify the products, but said it would send a letter to all of them, warning them that rosemary oil may be contaminated with potentially harmful chemical compounds.
It said that because of the nature of the topical treatments and the quantity of products distributed, it would consider the products to be safe to use as a topical agent.
The FDA has issued warnings to several brands of topical creams and gels containing rosemary, including ones sold at Walgreens and the National Health and Beauty Council, because of potential risks for allergic reactions.
The cosmetics maker said it has received more than 1,000 reports of possible allergic reactions related to the rosemary and is working with the FDA and the Food & Drug Administration to resolve any concerns.
The company, which also sells a topical cream, said the products contain the chemical compound phenylbutylmethylcarbamate (PBMC), which is known to cause serious allergic reactions in some people.
The products sold at pharmacies and other retail stores have the chemical listed as a “preservative,” but they do not have any ingredient that the FDA considers to be a “suspected ingredient,” the FDA wrote in a statement.
The department said it is now taking the products off the market, but they can be purchased at drugstores.
The brand that sells rosemary products is Healthwise Inc, and it does not have a presence on the U.S. Drug Enforcement Administration’s list of known or suspected drug manufacturers.
The product’s maker, Healthwise, did not immediately respond to a request for comment.
Rosemarie is the dried flower of the herb rosemary thaliana.
The dried flower is commonly used in Asian medicine for a variety of ailments.
The chemical was detected in the topical treatment products that were distributed in June and July of this year.
The FDA said it identified the chemical in batches distributed in October, November and December.
The drug maker said the FDA found the chemical by conducting a comprehensive review of its product testing.
The drugs, including a topical gel that is a blend of three products marketed by Healthwise for use on the scalp, were distributed to patients who attended its pharmacy, according to the company.
The company did not say how many patients attended the pharmacy, nor how many were prescribed the product.
In addition to the three products, Healthway is selling two other products that contain rosemary that were not sold by Healthway, the company said.
The first product is a cream that was sold at Walmart.
The second product is the topical gel.
Healthwise did not respond to requests for comment on how the products were distributed.
A Healthwise spokeswoman declined to comment on the investigation.
The Associated Press reported that Rosemary Oil is a commonly used product in Asian herbal medicine, and the company did in fact test the product on its website and found it did not contain any of the chemicals listed in the U-2 travel alert issued in February.
A number of products sold in stores and online at pharmacies are now subject to a U-6 alert, which states that the product may be unsafe for people with or sensitive to the chemicals.
Rose marie, also known as a rosemary herb, is also known for its anti-inflammatory properties.
In March, a product called The Rosemary Essence was recalled by the U.-2 travel advisory, which noted that the ingredients listed on the package could cause a skin reaction in people who have already had a reaction to another ingredient, including rosemary extract.
In January, Health Wise announced it was recalling products that contained rosemary for use by people with skin allergies.
The Food and Consumer Protection Agency has said that the chemical is known as phenylcyclohexane methanol, or PGME.PGME, or phenyl cyclohexanone, is used in the chemical form of epoxy resins, or epoxy, which are commonly used for insulation.
It can also be used in plastics, such as PVC.
The chemicals are often found in plastics used in food packaging, according the agency.
The Rosemary Essential Oil contains PGME and is considered safe for general use, the agency said in its March advisory.
Rose Marie is an herb, so it can cause skin irritation and allergic reactions, according a 2015 study by the
