Citrus paradisi seed extract (GSE)
Grapefruit seed extract is derived from the seeds of the citrus fruit Citrus paradisi. It is primarily used as an antimicrobial and antiseptic agent, often added to topical creams, oral rinses, and natural health products to help fight bacteria and fungi. Because it can inhibit the enzyme CYP3A4, it may raise the levels of certain medications (such as anticoagulants, statins, and some birth control pills); it can also contain synthetic preservatives that may cause irritation or allergic reactions, so usage should be monitored, especially when taken alongside prescription drugs.
