Understanding the Active Ingredients
Rawleigh's formula relies on a trio of active ingredients, each contributing a specific therapeutic action. These components work together to provide the soothing, penetrating effects the ointment is known for, particularly for respiratory and minor pain relief.
Camphor
Camphor is a potent topical analgesic and cough suppressant.
- Analgesic Effect: It creates a cooling sensation that can temporarily numb the area it is applied to, distracting the brain from deeper pain signals. This makes it effective for minor muscle aches and pains. It stimulates nerve endings, which can also provide a feeling of warmth in addition to cooling.
- Cough Suppressant: When applied to the chest, the vapors released from camphor can be inhaled, acting as a cough suppressant by clearing nasal passages and soothing throat and bronchial irritation associated with the common cold.
Menthol
Menthol is a natural compound found in peppermint and other mint oils. Like camphor, it is a key active ingredient that functions as both a cough suppressant and topical analgesic.
- Cooling Sensation: Menthol provides a powerful cooling effect on the skin and mucosal membranes. This sensation offers immediate, temporary relief from minor pain and irritation.
- Decongestant Action: The potent aromatic vapors from menthol, when inhaled, help to clear stuffy nasal passages and ease breathing difficulties caused by congestion.
Eucalyptus Oil
Distilled from the leaves of the eucalyptus tree, this oil is a well-regarded decongestant and antitussive (cough suppressant).
- Aromatic Vapor: The strong, pleasant aroma of eucalyptus oil is the basis for its use in chest rubs and inhalants. It helps to loosen mucus and phlegm in the respiratory tract.
- Soothing Effect: The vapors help to calm irritated airways and can provide relief from coughing associated with colds.
The Role of Inactive Ingredients
The base of Rawleigh medicated ointment is a blend of inactive ingredients that give it its salve-like consistency. These components ensure the active ingredients can be easily spread and absorbed by the skin while also providing a protective and moisturizing barrier.
List of inactive ingredients:
- Refined Petrolatum: A purified form of petroleum jelly, this is the main base of the ointment. It serves as a protective layer on the skin, preventing moisture loss and protecting minor cuts and scrapes.
- Mineral Oil: A lightweight oil that helps to spread the ointment smoothly over the skin.
- Paraffin: A wax-like substance that adds firmness and structure to the ointment.
- Hydrogenated Vegetable Oil: Provides texture and consistency to the product.
- Ceresin: A hard, white, waxy substance that also helps thicken the base.
- Cocoa Butter: A natural fat that adds a soothing, emollient property to the ointment.
Historical Formulation Changes
For consumers of a certain age, there is sometimes confusion about what are the ingredients in Rawleigh medicated ointment due to its long history. Older, historical formulations of Rawleigh products, as documented by institutions like the Smithsonian, included ingredients no longer used today. A key example is mercuric chloride, which was present in some early Rawleigh products but is not in modern formulations due to safety and regulatory reasons. The modern, reliable formula focuses on the potent combination of camphor, menthol, and eucalyptus oil in a safe, soothing base.
