Filled with 100% natural flaxseed and optional aromatherapy herbs (lavender, peppermint, or chamomile), this reusable heating pad delivers soothing moist heat that helps relax tight muscles and ease discomfort.
Simply microwave for 20–30 seconds for comforting heat therapy, or place in the freezer for 2+ hours for cooling relief. The flexible design allows the pad to contour naturally to your body, making it ideal for targeted relief.
What Can This Microwavable Heating Pad Help With?
- Menstrual cramps and period pain
- Lower back pain and sciatica
- Muscle aches and soreness
- Sports injuries and strains
- Arthritis and joint stiffness
- Post-surgical recovery
The natural weight of flaxseed allows the heating pad to gently mold to your body, delivering consistent heat exactly where you need it.
Why Choose Flaxseed Instead of Rice?
Flaxseed is widely considered the best filling for microwavable heating pads because it retains heat longer and distributes warmth more evenly.
- Retains heat 2–3 times longer than rice (20–30 minutes vs. 10–15 minutes)
- Produces soothing moist heat that penetrates deeper into muscles
- Conforms comfortably to your body for targeted relief
- Won’t mold, attract pests, or develop odors over time
The 6" x 12" size is ideal for treating larger areas such as the lower back, abdomen, shoulders, or thighs.
How to Use Your Microwavable Heating Pad
- Heat in the microwave for 20–30 seconds for soothing moist heat therapy
- Place in the freezer for 2+ hours for cooling relief
- Apply to the lower back, abdomen, shoulders, or other sore areas
- Use during rest, relaxation, or recovery after exercise
