Patients comes to shaman with white lesion in mouth cavity followed by difficulty to swallow. Literature study explain Pseudomonas aeruginosa a Gram positive bacterial, Gram negative Streptococcus mutans or fungal infections from Candida albicans are commonly causing mouth infections. Various parameters such as determination of Bedawob Mirah, fractionation with different solvent and their activity against Pseudomonas aeruginosa, Streptococcus mutans and Candida albicans also had been investigated. Plant determination showed that Bauhinia pottsii G. Don was the scientific name of Bedawob Mirah. Bacterial inhibition diameter both of Gram positive and negative bacterial showed that aquadest fraction had higher activity followed by n-hexane fraction and ethyl acetate fraction consecutively. Antifungal activity tested showed that n-hexane fraction had the higher diameter zone followed by aquadest fraction and ethyl acetate fraction. Key-words: Bauhinia pottsii G. Don, Dayak Mualang, Traditional Medication INTISARIAir rebusan akar Bedawob Mirah secara tradisional telah digunakan oleh suku dayak Mualang di Kalimantan Barat dalam pengobatan penyakit rabak di rongga mulut dengan penampakan lesi putih dan keluhan sulit menelan. Studi literatur menunjukkan infeksi rongga mulut dapat disebabkan oleh beberapa mikroorganisme diantaranya bakteri Gram positif seperti Streptococcus mutans, Gram negatif Pseudomonas aeruginosa dan jamur Candida albicans. Penelitian tentang uji aktivitas antibakteri dan antijamur ekstrak akar Bedawob Mirah telah dilaksanakan. Hasil determinasi tanaman menyatakan bahwa nama ilmiah Bedawob Mirah adalah Bauhinia pottsii G. Don. Ekstrak tanaman kemudian difraksinasi dengan etil asetat dan n-heksan. Hasil uji aktivitas antibakteri terhadap kedua bakteri uji menunjukkan fraksi air memiliki aktivitas tertinggi diikuti fraksi n-heksan dan fraksi etil asetat. Hasil aktivitas antijamur terhadap jamur uji menunjukkan bahwa fraksi n-heksan memilik aktivitas tertinggi diikuti fraksi air dan etil asetat. Kata kunci: Bauhinia pottsii G. Don, Dayak Mualang, Pengobatan Tradisional]]>
