Mentholatum Reviews 

Bought a deep heat roll on in September 2025 from Tesco, have used deep heat roll on previously and found it beneficial, but this new herbal one is absolutely rubbish a waste of money gives no heat at all no matter how much you apply and the smell isn't pleasant either did complain to the menthalatum co. and eventually was reimbursed with a £6.00 Amazon voucher but would rather have a product that worked like it used too

Adhesion properties of the deep heat actiflex patches absolutely useless- won’t stick to skin. Appalling performance- don’t buy this rubbish product

This company Manufactures the DeepHeat patches used to relieve complaints such as back ache.
My Wife has been using this product for years, it was her 'go to' whenever she had a back pain. However, several weeks ago, when she applied a patch, she noticed that the adhesive seemed different. It seemed a lot stronger. After 30 minutes or so she felt a burning sensation and had to remove the patch. It left her with a bad chemical burn that took a couple of weeks to clear.
Mentholatum were contacted immediately, and given pictures of the effect, along with batch information, and where and when purchased, and the use by date. In return for this, I was contacted by Joy Furrie to be told the Company took these things seriously. Sadly, all their serious efforts amounted to, was to email a PDF complaints form that seemed un-editable. I replied, to state that my primary e-mail contained all the information needed to cross check their batch.
That was the end of the process! They haven't even asked for the product to be returned for testing! Very strange methinks.

I use the Deep Freeze spray for pain relief on troubled joints and it does help.
The relief is quite short lived after the initial tingling fades but useful for small injuries.
