Ingredient review
Chenopodium Ambrosioides Extract
INCI: CHENOPODIUM AMBROSIOIDES LEAF/STEM EXTRACT
A traditional herb extract with potential antimicrobial benefits, but limited modern research and a risk of skin irritation for sensitive types.
In plain English
This is an extract from the leaves and stems of the epazote plant, also known as Mexican tea. In skincare, it's added for its traditional reputation as a cleansing and soothing ingredient. However, because the plant contains strong essential oils, it can be irritating for some people, and there isn't much high-quality research to confirm its benefits on skin.

What it is
A botanical extract derived from the Chenopodium ambrosioides plant (epazote), containing volatile oils like ascaridole and limonene that give it a strong aroma and potential antimicrobial activity.
How it works
The extract's essential oils may help reduce certain bacteria on the skin's surface, which could be useful in products aimed at blemishes. It also provides some antioxidant activity from its phenolic compounds. However, the ascaridole content can be sensitizing, especially at higher concentrations.
Pros
Traditional antimicrobial
Has a history of use in folk medicine for cleansing, which may translate to helping reduce blemish-causing bacteria on skin.
Antioxidant content
Contains phenolic compounds that can help neutralize free radicals, offering some protection against environmental damage.
Cons and cautions
Irritation potential
The essential oils, especially ascaridole, can cause redness, stinging, or allergic reactions, particularly for sensitive skin types.
Weak evidence base
Most benefits are based on traditional use or lab studies; there are few well-controlled human trials proving its effectiveness in skincare.
Best for
- People with oily or blemish-prone skin looking for natural antimicrobial options
- Those who tolerate herbal extracts well and want a traditional botanical ingredient
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
- Anyone with a known allergy to plants in the Amaranthaceae family
Usage tips
Safety summary
Chenopodium ambrosioides extract is considered safe for most people in low concentrations, but its essential oil content poses a moderate risk of irritation and sensitization. It should be avoided by those with sensitive skin or plant allergies. Pregnant or nursing individuals should consult a doctor due to traditional internal use concerns, though topical use is generally low-risk.
Research notes
Research on this extract in cosmetics is limited. In vitro studies show antimicrobial activity against some skin bacteria, but human clinical trials are lacking. Most evidence comes from traditional use and laboratory data, so its efficacy remains unproven in modern skincare science.
Common label clues
- Typical concentration
- Typically used at 0.1–1% in leave-on products
- Regulatory status
- Generally recognized as safe for topical use in cosmetics when used at low concentrations, but not specifically approved by the FDA for any medical claim.
- Common uses
- Facial cleansers, Masks, Treatments targeting blemishes
- Environmental note
- Epazote is a hardy, fast-growing plant that can be cultivated with minimal water, making it a relatively sustainable botanical source.
Good to know
- Epazote is also a culinary herb in Mexican cuisine, but the skincare extract is different from the fresh herb.
- The plant's strong scent can be off-putting in cosmetic products, so it's often blended with other botanicals or fragrances.
