Chinese Black Olive (Wu Lan / Buah Keranji Hitam / Hei Lan / Mu Wei Zi). Oblong purplish-black drupes with rich pulp and hard 3-edged stone. Sovereign for Chronic Pharyngitis & Bowel Lubrication: salted black olive pulp clears hoarseness and throat burning, sweet oily kernels lubricate dry constipation.
