Parietaria Officinalis (pellitory-of-the-wall) extract is a plant-derived ingredient used in cosmetics primarily for its purported emollient and skin-conditioning properties. It is not a clinically established treatment active and is more often included as a supplementary botanical component.
| Reported effect | How often | Notes |
|---|---|---|
| Allergic contact dermatitis | Rare | Possible in individuals sensitized to the plant; redness, itching at application site. |
| Respiratory/cross-reactivity sensitization | Rare | Parietaria is a known potent aeroallergen (pollen); topical use is not the same exposure, but atopic individuals may react. |
| Skin irritation | Very rare | Mild transient stinging or erythema reported with botanical extracts generally. |
