Although there are many patient reports of benefit from CBD in essential tremor, and while the internet is full of dosage recommendations, there is little in the medical literature to guide an answer to your question. CBD has a remarkably benign toxicity profile, and this makes cautious experimentation a plausible strategy. I would only consume CBD products from a medical cannabis dispensary, trying to avoid industrial hemp based sources, and I would consider using not just one of the 100 cannabinoids but perhaps a more holistic preparation also containing some THC, or perhaps whole plant extract from cannabis bred to express mostly CBD (eg. Harlequin strain). Essential tremor often waxes and wanes with stress level, intensity of attention, and many other factors influenced by cannabis, and the relaxation cannabis can promote might be an important factor.
