But first, a little CBD 101…
What are tinctures specifically?
CBD tinctures are generally made from high CBD strains of hemp, with 60 to 70 percent alcohol, and are primarily used to help relieve anxiety or ease pain. “Tinctures are convenient, have a long shelf life, and are absorbed easily when taken under the tongue. The dose can be adjusted by increasing or decreasing the number of drops taken,” notes Low Dog.
So are there side effects?
According to Low Dog, a tincture may offer a broader range of compounds from hemp than an oil extraction. “Consumers who are alcohol-sensitive often prefer hemp oil over tincture. While both can be used topically, hemp oil is generally easier to apply and less irritating,” she says.
CBD's exact mechanism of action is unclear.
It would be hard to overdose on CBD oil because human tolerance is very high. One study reported the toxic dose would be about 20,000 mg taken at one time.
The tricky part is calculating the exact amount of CBD per milliliter of oil. Some tinctures have concentrations of 1,500 mg per 30 mL, while others have 3,000 mg per mL (or more).
