Pu-erh tea

„Pu-erh tea processing, although straightforward, is complicated by the fact that the tea itself falls into two distinct categories: the "raw" Sheng Cha and the "ripe" Shou Cha. All types of pu-erh tea are created from máochá (毛茶), a mostly unoxidized green tea processed from a "large leaf" variety of Camellia sinensis (C. sinensis assamica) found in the mountains of southern Yunnan.“

„Some more obvi­ous man­i­fes­ta­tions of cha qi are a heat­ing or cool­ing of the extrem­i­ties (eg, sweaty palms when drink­ing a ‘warm­ing’ tea like aged puerh or heav­ily roasted oolong), a flush­ing of the face, or a mea­sur­able change in mood. In a small group, tea can either lead to deep con­ver­sa­tion, giddy laugh­ter, or con­tem­pla­tive silence.“
