Better than a hot water bottle

I love that I can wear this while working or sleeping. It provides gentle, continuous heat without needing to refill water. The motherwort addition seems to help with relaxation too.

Very warm and effective

These get hotter than I expected, which is nice for severe cramps. Just make sure you don't put it directly on bare skin to avoid irritation. The herbal smell is pleasant.

Essential for cold days

Not only do I use these for period comfort, but also just to keep my core warm during cold weather. They are discreet under clothes and work instantly once opened.

Lifesaver during my cycle

These patches provide consistent warmth that really helps soothe cramps. The mugwort scent is calming and not overpowering. I will definitely buy again.

Good heat, stays on well

The adhesive is strong enough to stay on my underwear without slipping. It gets quite warm, so be careful if you have sensitive skin. Overall a great product for winter.

Highly recommend for period pain

I have tried many brands, but Renhe seems to last the longest. The heat distribution is even across the whole patch. Great value for money.

5 FAQ

Q: What is the shelf life of these patches?

A: When stored in a cool, dry place away from direct sunlight, the patches typically have a shelf life of 3 years from the manufacturing date printed on the box.

Q: Can men use these patches for back pain?

A: Absolutely. While marketed for period relief, the self-heating mugwort technology is effective for soothing general muscle stiffness, back pain, or keeping the body warm for anyone.

Q: How long does it take to start heating up?

A: Once you remove the protective liner and expose the patch to air, it typically begins to generate heat within 10 to 15 minutes.

Q: Is this safe for sensitive skin?

A: The patch is designed to be applied to clothing over the abdominal area. If you have very sensitive skin, we recommend placing a thin layer of fabric between the patch and your skin to prevent any potential irritation from the heat.

Q: Can I sleep with this patch on?

A: Yes, many customers use them overnight. However, please ensure it is applied to your clothing, not directly on your skin, and check that the temperature feels comfortable before falling asleep.
