Neither passport's own pairing or caution list mentions the other. That is an absence of a recorded relationship, not a statement that combining them is safe -- see each ingredient's own passport for what it does say.

Concerns addressed	Redness & sensitivity Barrier repair	Breakouts & congestion Oil & pores Redness & sensitivity
Before you start	Documented as a weak sensitizer; may cause allergic contact dermatitis when applied repeatedly to severely compromised or post-procedure skin.	Exceedingly gentle and well-tolerated on all skin types. Rare instances of mild localized sensitivity or redness may occur, and those with rare plant allergies should patch-test first.
Contraindications	Published case reports describe hepatotoxicity (liver injury, including jaundice and granulomatous hepatitis, with one case recurring on re-exposure) following oral ingestion of Centella asiatica as an herbal remedy or dietary supplement; this concern is specifically tied to oral ingestion, not topical cosmetic use, and no report of topical hepatotoxicity was located [S014]. Separately, no published report of photosensitivity or a phototoxic reaction to topical Centella asiatica extract was located in this research -- an explicit absence of evidence, not a demonstration of safety in sun exposure.	A dedicated search of the peer-reviewed literature did not locate any documented contraindication for topical Houttuynia cordata extract as a cosmetic ingredient, distinct from the injectable-form safety signal disclosed in allergen_history above, which does not apply to topical use.
Use with caution	Individuals with known plant allergies (Apiaceae family) or diagnosed cosmetic contact dermatitis.	Nothing recorded yet
Pause first	Active allergic contact dermatitis Known sensitivity to Apiaceae family plants Post-procedure skin experiencing active eczema flare-ups: Raw botanical fractions can trigger rare contact sensitization in highly broken barriers.	Nothing recorded yet
Boundary	Anti-wrinkle miracle: While Centella stimulates collagen in vitro and improves scar thickness clinically, it cannot replace medical-grade retinoids or injectables for deep wrinkle reversal. Acne curing: Centella calms active inflammation, but it does not possess salicylic acid's pore-clearing (lipophilic) or benzoyl peroxide's direct antibacterial activity against C. acnes.	The 4.6-fold sebum reduction and moisture benefits demonstrated with leave-on facial toners cannot be directly translated to quick-rinse foaming cleansers due to significantly lower skin contact time. The localized anti-inflammatory and cellular photoprotective effects observed with topical extracts cannot be equated to the systemic immunomodulatory results of oral Houttuynia cordata dietary supplementation. Preclinical in-vitro models showing NF-kB pathway suppression in isolated human mast cells do not guarantee identical therapeutic efficacy in repairing deeply compromised human skin barriers without appropriate cosmetic delivery vehicles.

Deep-dive Q&A

Centella asiatica

Why is Centella asiatica often called 'Cica' or 'Tiger Grass' in skincare?

**A:** The term 'Cica' is a marketing abbreviation derived from 'Centella asiatica'. The historical name 'Tiger Grass' originates from traditional observations in Asia, where wounded tigers were observed rolling in wild Centella asiatica patches to heal their wounds. This botanical folklore has been scientifically validated, as modern research demonstrates that Centella's triterpenoids accelerate cellular repair and wound contraction [S004, S009].

Can I use Centella asiatica if I have extremely sensitive, eczema-prone skin?

**A:** Yes, Centella asiatica is highly recommended for sensitive and eczema-prone skin due to its potent anti-inflammatory and barrier-strengthening properties. However, because raw plant extracts can contain trace botanical impurities that act as weak sensitizers, individuals with severely compromised barriers should perform a patch test on their inner forearm for 3 consecutive days before facial application [S007].

What is the difference between a product with '95% Centella Extract' and '0.2% Madecassoside'?

**A:** This is a common source of confusion in cosmetics. A '95% Centella Extract' usually refers to a bulk raw material where dried Centella is steeped in a solvent (typically water and glycols); the actual active molecule concentration in this extract is often less than 0.1%. Conversely, '0.2% Madecassoside' represents a highly purified, isolated active compound that is standardized and tested at precise therapeutic levels. Purified active markers (like Madecassoside or TECA) are significantly more potent and reliable than bulk crude extracts [S006, S008]. ---

What is the biological mechanism and dermatological evidence for Centella Asiatica Extract in skincare?

Centella Asiatica Extract (Centella Asiatica Extract) functions as a Botanical Extract. Botanical extract rich in asiaticoside, madecassoside, and asiatic acid that dampens IL-1beta and TNF-alpha.
