What Is Plectranthus Amboinicus Leaf/Stem Oil?
Plectranthus Amboinicus Leaf/Stem Oil is an aromatic oil obtained from the leaves and stems of Plectranthus amboinicus, a fragrant herb in the mint family often called Indian borage or Cuban oregano. The fresh plant parts are steam distilled, a process that passes hot water vapor through the chopped leaves and stems to lift out the volatile, oil-based compounds. The resulting oil contains a mix of terpenes, flavonoids and small amounts of fatty acids that give it a distinct herbal scent and the ability to soften and smooth the skin.
The plant has been used for centuries in traditional cooking and home remedies across Asia, Africa and the Caribbean. Its pleasant aroma and soothing feel on the skin drew the attention of cosmetic formulators in recent decades. As natural and botanical ingredients gained popularity, manufacturers began adding the distilled oil to creams, balms and specialty treatments to provide a gentle conditioning effect along with a fresh, green fragrance.
Today you will most often find Plectranthus Amboinicus Leaf/Stem Oil in moisturizers, overnight masks, nourishing body butters, after-sun lotions and targeted serums aimed at calming dry or stressed skin.
Plectranthus Amboinicus Leaf/Stem Oil’s Cosmetic Benefits/Uses
This ingredient is valued for one key role in skin care formulas.
Skin conditioning: The oil helps maintain soft, supple skin by forming a light protective layer that slows moisture loss. Its blend of terpenes can leave the surface feeling smoother and more comfortable, which is why formulators often include it in products designed for dryness, rough patches or post-exfoliation care.
Who Can Use Plectranthus Amboinicus Leaf/Stem Oil
This botanical oil is generally well tolerated by most skin types including dry, normal, oily and combination skin thanks to its lightweight texture and soothing nature. People with easily triggered or highly sensitive skin should proceed with a bit more caution since any fragrant plant oil can pose a risk of irritation when used at high levels.
The ingredient is plant derived so it is suitable for vegetarians and vegans. No animal sourced substances or animal testing are required to obtain or process the oil in standard cosmetic manufacturing.
Current research shows no specific risks for pregnant or breastfeeding women when the oil is used topically in the low concentrations found in finished cosmetics. Even so this is not medical advice and anyone who is expecting or nursing should check with a healthcare professional before adding new products to a routine.
Plectranthus Amboinicus Leaf/Stem Oil is not known to cause photosensitivity. Normal sun protection measures should be followed as usual but there is no special need for added caution in daylight because of this ingredient.
Potential Side Effects/Adverse Reactions
Side effects from topical use of Plectranthus Amboinicus Leaf/Stem Oil can vary from person to person. The points below outline potential issues yet most users will not experience them when the ingredient is used at the low levels typical in finished products.

Comedogenic Rating
Rating: 1 out of 5. Plectranthus Amboinicus Leaf/Stem Oil is composed mainly of lightweight volatile compounds rather than heavy waxes or long-chain fatty acids that can build up inside pores. Because it evaporates or absorbs quickly it is unlikely to clog follicles, earning it a low score of 1. This makes the oil generally fine for people who are prone to acne or frequent breakouts. The only users who might notice congestion are those whose skin reacts to virtually any fragrant essential oil, though such cases are uncommon.
Summary
Plectranthus Amboinicus Leaf/Stem Oil acts primarily as a skin-conditioning agent, laying down a thin breathable layer that helps keep water in and leaves the surface feeling smoother. Its natural terpenes also lend a fresh herbal scent that can enhance the sensorial experience of creams, balms and serums.
While not as famous as lavender or tea tree, the ingredient enjoys quiet popularity among formulators looking for niche botanical options that condition without heaviness. You are most likely to see it in mid-tier or artisanal products aimed at dry or mildly irritated skin.
Overall safety is high when the oil is used at the low percentages common in finished cosmetics, with irritation mainly a concern for those already sensitive to fragrant plants. As with any new skincare product it is wise to perform a quick patch test to spot potential issues before applying more broadly.
