The kava buyer was told to always purchase the lateral roots and rootlets (called waka in Fiji) as the best drink was prepared from them. Next in preference were the thickened underground parts of the stem and stump comprising the rhizome (lewmd). The kasa (the first few nodes and internodes of the stem or stalk) of the plant was acceptable only if the waka or lewma was unavailable. On no account was already powdered kava to be used, as it might have been derived from the stalks, or a mixture of stalks and root, and there was the possibility of adulteration with sawdust, flour, soil, or other contaminants. Furthermore, the drinkers often examined and smelled the rootstock for freshness as deterioration occurs with storage (Duve and Prasad, 1983). In addition to potency, the older material also loses its characteristic odor and flavor, both of which are highly relished by the drinkers. 

In contemporary Fiji, Samoa, and Tonga, producers process dried kava by pounding this in makeshift mortars (hollow tree stumps or metal pipes) using a variety of wooden or metal pestles. Instead of filtering kava grounds from the bowl after infusion — the traditional technique — kava makers today may first wrap powdered kava in scraps of cloth and then squeeze this bundle in water to leach out kavalactones without getting grounds into the drink. 

Into the flask, put about 150 ml of Liquid Fire drain opener. Next add 100 grams of potassium nitrate. This should either be a reasonably pure stump remover such as the Green Thumb brand, or a dirtier brand purified by the directions given in the nitric acid section. Lumps in the stump remover should be broken up so that a fine powder is added to the acid drain opener.
