Sir,

Since the real symptoms of having contracted COVID-19 and its variants or subvariants are generally cough, a runny nose, fever, and loss of taste, and since these alarms are not evident in asymptomatic patients infected with Omicron, especially children and young boys, and the only affordable evidence is a rapid or swab test, it is highly important to have other options to determine an infection with the Omicron variant, even if the patient does not feel anything at all [1,2].

Two types of skin rashes may be the distinguishing symptoms for individuals who have contracted Omicron and cannot be sure to have the variant (since no fever is one of the most evident signals of the real absence of SARS-CoV-2).

These two types of skin manifestations are:

1) prickly heat rashes,

2) urticaria or hives rash.

 

The first type of manifestation is detectable in the youngest and may appear anywhere on the body, yet is believed to have been most commonly found on the hands and feet, as well as the elbows. The second type is more similar to a hives rash and appears as raised bumps on the skin. While the first type is more persistent and may last for days or even weeks, the hive-like type tends to come and go in a much quicker fashion.

The skin symptoms discussed here are thought to be visible in some individuals with the virus who are not showing absolutely any other symptoms.

Heat rashes normally go away without treatment. However, there are medicines available to ease the symptoms of itching. These include calamine lotion (which helps ease itching) and antihistamine medicines.

Instead of calamine, even magnesia usta or alumina or, if possible, especially in countries in which the powder may be retrieved (in Scandinavia), deer-horn burnt amalgam, blanc d’Espagne or Tripoli, may be employed. These are the best powders to be the reputed vehicles to maintain the active ingredient in contact with the skin, even in the case of sweat or wet skin.

The best natural antihistamine is the butterbur, of the genus Petasites, flowering plants in the sunflower family, Asteraceae, which are commonly referred to as butterburs and coltsfoots [3,4]. They are perennial plants with thick, creeping underground rhizomes and large, rhubarb-like leaves during the growing season. Most species are native to Asia and southern Europe [35].

Applying butterbur to prickly rashes is a sort of Russian roulette, yet there is an ancestral Neapolitan adage that says: ndove c’è gusto non c’è perdenza (something to be used to abate an affliction is more desirable when the remedy itself is perilous and risky).

Effectively, butterbur extracts may contain harmful components called pyrrolizidine alkaloids if the preparation is not carefully and fully purified. The concentration of the toxic alkaloids is often the highest in the rhizomes and the lowest in the leaves, and may vary depending on where the plants are grown. Long-term health effects and the interaction of butterbur with other drugs have not been well documented. However, an interaction with St. John’s wort (topical use) may potentially lead to an increased concentration of the toxic alkaloids. Yet, it is obvious that those who use butterbur will never apply Hypericum perforatum extract or oil onto the skin.

A panel group of 12 boys and girls (12–24 yrs. old) showing prickly heat rashes and a panel group of 12 boys and girls (12–24 yrs. old) suffering from urticaria [3] (in the presence of a supposed Omicron infection) were recruited to attempt to apply a mash of butterbur to abate the first epidermal malaise or a fluid ointment to defeat the urticaria.

The following is the recipe for the first mash:

  • magnesia usta (magnesium oxide): 88%;

  • butterbur leaves in aqueous extract: 12%

 

Applications must be replicated for almost fourteen days twice a day. This remedy is only to allow the individual infected with Omicron to feel better.

As far as hive rashes or urticaria are concerned, it is better to employ an oily and fluid emulsion with castor oil (86%) and Solanum nigrum lipophilic extract (14%) [6].

Solanum nigrum is a perennial, infesting, and ubiquitous plant, and the unripe fruits and leaves are exceptional to produce a highly efficient liquor for defeating the itch of whichever hive rash.

One must keep in mind that urticaria, also known as weals, welts, or nettle rash, is a raised, itchy rash that appears on the skin and that may appear on one part of the body or be spread across large areas. The rash is usually very itchy and ranges in size from several millimeters to the size of a hand.

The application may be replicated for an entire week on the spots or onto the areas affected with urticaria. The prickly heat rashes disappear after the twelfth day and, in one case, after the fourteenth, while urticaria disappears after the sixth to seventh day of application.
