The Vicks Plant is a popular, strongly scented herb known for its powerful, familiar fragrance. Its common name is derived from the distinct aroma released when the leaves are brushed or crushed, which strongly resembles the mentholated vapor rub. Its appeal lies in its easy cultivation and the refreshing scent it brings to a living space.
Identifying the Vicks Plant and Its Origin
The Vicks Plant is scientifically classified as Plectranthus tomentosa, though it is sometimes listed as Plectranthus hadiensis var. tomentosus. It belongs to the Lamiaceae family, commonly known as the mint family. This perennial subshrub is native to the warm, dry regions of Southern Africa.
The plant has several common nicknames, including Succulent Coleus and Cuban Oregano. Its physical appearance is characterized by thick, succulent, broadly ovate leaves. These leaves are covered in a dense layer of fine, velvety hairs, giving the plant a fuzzy texture, which is reflected in the Latin species name tomentosa.
Cultivating the Vicks Plant Indoors and Out
Successful cultivation depends on providing conditions that mimic its semi-succulent, African origins, focusing on well-draining soil and appropriate light. The plant performs best in bright, indirect sunlight, such as a sunny window with filtered light. While it can tolerate some direct morning sun, intense afternoon sun can easily scorch its leaves.
Overwatering is the most common cause of decline, often leading to root rot due to its succulent nature. Water the plant thoroughly, then allow the top inch or more of the soil to dry out completely before watering again. The ideal growing medium is a well-draining, sandy or organic-rich mix, similar to what is used for cacti.
For indoor cultivation, the plant thrives in average room temperatures, typically 65 to 75°F. Regular pruning is recommended to encourage a more compact, bushy shape, as the Vicks Plant can grow quickly and become “leggy.” Propagation is easily achieved using the removed stems by taking a cutting below a leaf node and placing it directly into moist soil or water to root.
Why It Smells Like Vicks and Traditional Uses
The distinct Vicks-like scent is due to the high concentration of volatile organic compounds stored in the leaves, which are released when bruised. These compounds are terpenoids, which form the main constituents of many plant essential oils. Specific aromatic molecules identified include menthol and camphor, which are the same active ingredients that give Vicks VapoRub its characteristic smell.
Traditionally, the Vicks Plant has been used in folk medicine, particularly for respiratory ailments. A common practice involves crushing the leaves and steeping them in boiling water, allowing a person to inhale the resulting mentholated vapor to help clear congestion. The crushed leaves have also been rubbed directly onto the chest as a poultice or ointment, similar to the commercial vapor rub application.
It is important to understand that these are historical uses, and the plant has not been medically proven as a treatment for illness. Consultation with a healthcare professional is always advised before using any herb for medicinal purposes, and ingestion of the plant or its extracts should be avoided.
