La Vang
Many people sought refuge in the rainforest of La Vang in Quảng Trị Province, Vietnam, and many became very ill. While hiding in the jungle, the community gathered every night at the foot of a tree to pray the rosary. One night, an apparition surprised them. In the branches of the tree a lady appeared, wearing the traditional Vietnamese "áo dài" dress and holding a child in her arms, with two angels beside her. The people present interpreted the vision as the Virgin Mary and the infant Jesus Christ. They said that Our Lady comforted them and told them to boil leaves from the trees for medicine to cure the illness. Legend states that the term "La Vang" was a derivative of the Vietnamese word meaning "crying out". Another hypothesis is that La Vang is distorted from the toponym "Lá Vằng", "lá" meaning leaf and "vằng" meaning jasminum subtriplinerve, a tree species whose leaves are used to made a tisane; according to an ancient practice, a location was sometimes named after a prominent local species of plant or animal.
