Pure Botanika Pain Patches are the longest-lasting pain patch for back pain, on the market. Pure Botanika pain patches provide sustained pain relief lasting up to 96 hours. They are waterproof and sweatproof allowing you to set it and forget it. With the transdermal application, the pain and inflammation-fighting hemp oil get right to work without waiting to be absorbed by the digestive tract and liver, which can take time and also causes you to lose up to half of the active oil in the process. Pure Botanika Pain patches work for mild-to-moderate aches and pains of muscles and joints associated with arthritis, back pain, strains, bruises, and sprains.
