Science
Mechanism of Action
This extract operates by suppressing inflammatory mediators such as cyclooxygenase-2 (COX-2) and prostaglandin E2 (PGE2), while also stabilizing mast cells to reduce degranulation. It modulates cellular calcium channels, inhibiting Orai-1 to reduce T cell activation and activating TRPV3 to promote skin barrier repair and alleviate pruritus. Enriched with bioactive compounds like steroidal saponins, flavonoids, and alkaloids, it offers antioxidant benefits and exhibits antimicrobial efficacy against pathogens like *Staphylococcus epidermidis* and *Candida albicans*.

Key findings
- 01 A 2017 study demonstrated that 1% *Tribulus terrestris* fruit extract, when combined with 0.1% hydrocortisone, significantly mitigated symptoms of oxazolone-induced atopic dermatitis in mice. Observed effects included a reduction in skin erythema, edema, epidermal hyperplasia, and transepidermal water loss (TEWL). The extract effectively inhibited skin inflammation, decreased inflammatory cell infiltration, regulated Orai-1 and TRPV3 channels, and stabilized mast cells without inducing cytotoxicity.

Safety
Safety Profile
While generally regarded as safe at recommended doses, systemic use may lead to hormonal imbalances, mood fluctuations, or menstrual irregularities in some individuals. Rare instances of allergic reactions, including skin rashes or itching, have been reported topically. This ingredient is not an FDA-approved drug. Pregnant or breastfeeding individuals should avoid its use due to a lack of safety data. Individuals with hormone-sensitive conditions (e.g., prostate conditions, hormone-sensitive cancers) should consult a healthcare provider before use.
