Science
Mechanism of Action
This extract operates by modulating key inflammatory pathways, notably inhibiting the production of nitric oxide (NO) and prostaglandin E2 (PGE2), while also suppressing the gene expression of COX-2 and iNOS in inflammatory cells. It further reduces various pro-inflammatory cytokines such as TNF-α and IL-1β. Beyond its anti-inflammatory actions, it exhibits significant antioxidant capabilities through free radical scavenging, enhancing reducing power, and supporting the regeneration of endogenous antioxidant enzymes and glutathione levels. Additionally, it offers antibacterial and antifungal benefits and promotes cell proliferation in wound healing models.

The Formula
Formulation
Stability
β-Lapachone, a significant bioactive compound within Tabebuia, exhibits poor stability and limited water solubility (160 µM), posing a formulation challenge. However, extracts can be prepared using diverse solvents like water, ethanol, and ethyl acetate, indicating variable solubility based on the extraction method and desired compounds.
Safety
Safety Profile
While further human clinical trials are recommended for immunopharmacological effects and overall safety, animal studies have shown amelioration of atopic dermatitis without toxicity at tested concentrations. It is generally considered 'Irritant Free' and 'Teen SAFE' by SkinSAFE. It is important to note that β-Lapachone, a constituent, has shown toxicity at high doses, but this is differentiated from the safety profile of the extract as a whole.
