Id Highly recommend anyone to go and see Cassandra at Amber therapy. I have been using/ wearing my polished amber necklace for the past 6 months for knee and joint pain, and can i just say... AMAZING !! I no longer have to take anti-inflammatory or pain killers for my knee, which was almost a daily intake for many years. With my success I now have bought a collar for my 18 year old cat to assist with her arthritis while also giving her natural protection against fleas and ticks. Thank you so much Cassandra, you are amazing, and always so helpful!
