Better than electric heaters
I love that these are portable. I can wear them under my clothes while running errands. The adhesive stays on well even when moving around.

Good but takes time to activate
Once they get going, they are great. However, it took about 20 minutes after opening the package to feel significant heat. Plan ahead before applying.

A lifesaver during my cycle
These patches provide consistent warmth without getting too hot. The mugwort scent is very soothing and helps me relax. I wore one for a full workday and it lasted exactly as advertised.

Perfect gift for winter
Bought a bulk pack for my daughters and sisters. Everyone loves them. The packaging is nice and the refund guarantee gave me confidence to try them.

Great heat, strong smell
The heating effect is excellent and really helps with cramps. Just be aware that the herbal smell is quite potent, which I like, but might be overwhelming for some.

Tongrentang quality is trusted
I have used this brand for years. These new extra-long lasting patches are an improvement. They keep my lower back warm throughout the night.
Q: What is the maximum temperature reached?
A: The average surface temperature stabilizes between 45°C and 50°C (113°F - 122°F), designed to be warm and therapeutic without causing burns when used as directed.
Q: Can I sleep with these on?
A: Yes, many customers use them overnight. However, please ensure you apply it to clothing rather than bare skin and check that the temperature feels comfortable before falling asleep.
Q: Can these patches be worn directly on the skin?
A: We recommend applying the patch to your underwear or a thin layer of clothing to prevent direct contact, which ensures comfort and prevents potential skin irritation from prolonged heat.
Q: How do I activate the heat pack?
A: Simply tear open the individual outer packaging and expose the inner pad to air. The ingredients will react with oxygen to generate heat within 10 to 20 minutes.
Q: Is the scent artificial or natural?
A: The scent comes from real extracted mugwort and ginger ingredients included in the formula, providing a natural herbal aroma rather than an artificial fragrance.
