How to use it (and how to use it safely)

The Period Patch is an air-activated heat patch. It gets warm on its own and stays warm for up to six hours. Please read this before your first one.

How to use it

  1. Open the sachet. The patch starts warming as soon as it meets the air.
  2. Peel the backing and apply the adhesive side to clean, dry, unbroken skin on your lower abdomen or lower back.
  3. Always apply it over a layer of clothing if your skin is sensitive, and never directly under tight waistbands that press it into one spot.
  4. Wear for up to 6 hours. Remove it slowly, peeling back on itself.
  5. Dispose of the used patch with household waste. Do not flush it.

Important safety information

Sustained low-level heat against skin can cause a low-temperature burn even when it never feels too hot. This is the main risk with any heat patch, and it is easy to avoid.

  • Do not sleep in it. Prolonged pressure on a warm patch while you are asleep is the most common way people get burns from heat products.
  • Do not use with another heat source — hot water bottles, electric blankets, heat pads or heat rubs.
  • Do not apply to broken, irritated, sunburnt or recently shaved skin, or over a rash, scar or wound.
  • Check your skin regularly while wearing it. If it feels too hot, stings or itches, take it off.
  • Do not use more than one patch at a time on the same area.
  • Keep sachets, used and unused, away from children and pets. The contents are not for eating.
  • Discontinue use and seek medical advice if you get skin redness that doesn't fade, blistering, or pain.

Please speak to a doctor first if you

  • are pregnant, think you might be, or are breastfeeding — mugwort and dong quai are traditionally avoided in pregnancy, and we do not recommend using this product without medical advice
  • have diabetes, poor circulation, or any condition that reduces sensation in your skin
  • have a known allergy to any of the botanicals listed, or to adhesives
  • are taking anticoagulant (blood-thinning) medication
  • have an existing skin condition affecting the area
  • are using it on someone who cannot tell you they are uncomfortable

Not suitable for children.

What's in it

Heat layer: an air-activated blend of iron powder, vermiculite and salt.

Outer and adhesive layers: printed non-woven fabric with a skin-contact adhesive.

What this product is not

The Period Patch is a warming comfort product. It is not a medicine or a medical device, and it is not intended to diagnose, treat, cure or prevent any condition. The botanicals in it are included for their long history in traditional practice, not as a treatment.

Period pain that is severe, getting worse, or new to you is worth taking to a doctor. Heat is a comfort, not an answer, and conditions like endometriosis, adenomyosis and fibroids are commonly missed for years. Please do not let a warm patch stand in for a diagnosis.

Storage

Store sachets sealed, in a cool dry place, out of direct sunlight. Once a sachet is opened the patch begins to warm and cannot be saved for later.
