Gotu Kola Oil: Possible Skin Side Effects
Known as gentle on the skin, gotu kola oil isn't entirely immune to a skin reaction. Here's what documented cases show, and how to limit the risk.
Gotu kola oil (centella) is one of the best-tolerated Ayurvedic massage oils, but it isn't perfectly inert for the skin: cases of contact dermatitis linked to centella preparations have been documented in the medical literature, particularly with prolonged application on already-compromised skin.
A recent case of centella contact dermatitis
A study by Özkaya and colleagues, published in 2024 in the journal Contact Dermatitis, reports the case of two patients who developed eczema after repeated application of a 1% Centella asiatica ointment, used to support wound healing (see the study on Google Scholar). Patch tests confirmed sensitization to centella, with co-sensitization to certain fragrance allergens (lavender, geranium) in these patients. This case involved prolonged application on already-injured skin, a situation specifically discouraged in our reference article gotu kola oil — but it confirms that sensitization to centella remains possible, even if it stays rare.
The most common side effects
| Reported effect | Frequency | Most likely context |
|---|---|---|
| Greasy texture, slow absorption | Frequent | Normal characteristic of a macerated oil, not an adverse effect |
| Mild, temporary irritation | Occasional | Very sensitive skin or a poorly tolerated oily base (sesame, coconut) |
| Allergic contact dermatitis | Rare, documented | Prolonged application on injured skin (Özkaya et al., 2024 case) |
Distinguishing the massage oil from the oral extract
Our article gotu kola: side effects details the effects reported with centella taken orally (mainly digestive issues). These effects don't apply to the external massage oil, whose risk remains almost exclusively cutaneous and of a different nature.
How to limit the risk in practice?
- Test in the crook of the elbow 24 hours before first application, especially if you've already reacted to a fragranced skincare product;
- Never on an open, unhealed wound, the situation most associated with documented sensitization cases;
- Stop use if redness, itching or eczema appears or worsens after application;
- Check the oily base (sesame, coconut) if you have a known food allergy to either ingredient.
Precautions
Used on intact skin and after a prior skin test, gotu kola oil retains a reassuring tolerance profile: the documented dermatitis cases involve prolonged use on already-injured skin, not a classic massage on healthy skin.

Your questions about gotu kola oil
Can gotu kola oil cause an allergy?
It's possible but rare: a 2024 study documented two contact dermatitis cases after prolonged application of a centella ointment on already-injured skin. A prior skin test is still recommended before any regular use.
Can you apply gotu kola oil to a wound?
No, not on an open, unhealed wound: that's exactly the context linked to the rare documented sensitization cases. It suits intact but fragile skin better, as a preventive measure.
What is the difference between the side effects of the oil and centella capsules?
Capsules taken orally can cause digestive issues. The massage oil used externally carries an almost exclusively cutaneous risk, of a different nature and overall rarer.
What should you do if a skin reaction occurs with gotu kola oil?
Stop applying it, rinse with clean water, and see a doctor or dermatologist if redness or itching persists beyond a few hours or worsens.
