Every batch of kombucha is different. The only things every batch contains are: (1) at least one beneficial yeast, (2) acetobacter (the beneficial bacteria in the SCOBY), (3) gluconic acid (a pH regulator) – note: this is not the same thing as glucuronic acid referenced above, and (4) acetic acid (an anti-microbial acid, which also stabilizes blood sugar) . Most batches of kombucha will also contain an analgesic (pain reliever), an anti-arthritic compound, an anti-spasmodic compound, a liver-protective compound, and several anti-bacterial compounds. The blend varies from batch to batch. See why this elixir can’t be patented? It embodies change.
