It is manufactured by Ginebra San Miguel, formerly La Tondeña Inc. It is made from 14 authentic Chinese botanical herbs.
2. It is named after a Pinoy [komiks]] jungle hero, Kulafu. On July 7, 1933, Francisco Reyes, a pioneer komiks creator, in collaboration with writer Pedrito Reyes, created the legend of Kulafu, who was modeled after Tarzan. Kulafu was serialized in the Liwayway from 1932-1941, and became so famous it developed into a household name. Ginebra San Miguel, Inc. purchased the rights to the "Kulafu" name and since then Vino Kulafu has sold steadily. It is considered the main elixir of peasants in the countrysides of Visayas and Mindanao.
