The Arctic "Uva-Ursi" of the Boreal Tundra

1. Arbutin & Hydroquinone Biotransformation

• Targeted Urinary Antiseptic: In the bladder (specifically in alkaline urine with $\text{pH} \ge 7.0$), Arbutin is enzymatically hydrolyzed by bacteria into free Hydroquinone, which exhibits strong direct antimicrobial action against uropathogenic bacteria.
• Short-Term Use Rule: Safe and effective for acute 5 to 7 day episodes; not intended for long-term continuous maintenance.
