Today we’re talking about the process which led to the cultivation of Piper Methysticum (Kava). Kava is special, as very few other species are subjected to such intense selection pressure on individual plants. Kava is planted, tended to for 2-4 years, and then harvested and processed for consumption. Normally the plant was ground and consumed that day. The farmers would then make a decision about whether that plant provided positive, different or interesting effects. If the kava provided a positive physiological effect, nodes were re-planted of the original plant which was harvested, continuing the line of genetic clones. If the plant didn’t provide what the farmer judged as a “positive” effect, the plant remains were buried and that mutation line was effectively removed. Through thousands of generations of this type of selection, Piper Wichmannii was crafted into the cultivated form, Piper Methysticum.
In the figure attached it is shown a proposed lineage of chemotypes where humans effectively cultivated wild kava into the kavas we know and love today. Wild kava chemotypes typically began with DHM (#5) as the most abundant kavalactone. Through the purposeful selection efforts as described, farmers continually sought kavas lower in DHM and higher in Kavain (#4). During this process, DHM and K have been effectively swapped.
When you drink your kava tonight raise your shell to the careful and considerate actions of kava farmers from hundreds, or possibly thousands of years ago all the way up to today. They’re the reason we have this wonderful plant.
