I do not recommend the use of raw tongkat ali powder. Raw tongkat ali is not fit for human consumption. Tongkat ali is a root growing in soil. Soil anywhere in the world contains bacteria and fungi, among them E. coli bacteria and salmonella bacteria. Both species exist in strains that can be fatal to humans. Raw tongkat ali would have to be cooked as tea, best for half hour. Now, try that with tongkat ali root powder. This tea is absolutely awkward to filter. If anybody buys tongkat ali that has not been processed as extract, then better buy root chips, not root powder.
