For thousands of years, the oak has been viewed as a symbol of endurance and vitality, and for good reason. For example, there is an oak in California which is believed to be 13,000 years old, making it the longest living being on earth. And, as you might expect, the symbolic qualities attributed to the tree can actually be found as therapeutic properties in its fruits.

Like most fruits, acorns are a good source of vitamins and minerals, though they also contain a great deal of tannins, which give them a rather unpleasant bitter taste. But their true value might be in certain substances that have been proven to have inhibitory effects on glutamate-induced calcium signaling and on acetylcholinesterase.

A study published in European Journal of Clinical Pharmacology in 2012 demonstrated that “in terms of the effect, a 2-g single dose of acorn extract showed acetylcholinesterase inhibition (about 5%) similar to that of a 16-mg single dose of galantamine, in the first 24 h after administration.” This inhibitory effect makes acorns a suitable candidate for treating myasthenia gravis, glaucoma, postural tachycardia syndrome, Alzheimer’s disease, Lewy body dementia, Parkinson’s disease, autism, cognitive impairments associated to schizophrenia etc.
