Why menstruflow?

Polina, one of the founders, was lying on the sofa on holiday with severe period pain. All plans had to be cancelled, and the frustration was huge. She asked herself: are there really no alternatives to the pill or painkillers?

After intensive research into the use of TENS devices for muscle pain, the idea arose to use them for period pain as well. After discussions with Dr med Ulrike Lange, menstruflow was founded. With ONEflow, the company is developing a TENS device specifically for people who menstruate and experience pain and cramps. Polina wouldn’t want to be without it now!

menstruflow goes to Indonesia

menstruflow’s journey began in Germany, where ONEflow has already helped more than 10,000 women find relief from period pain and endometriosis, supporting them in reclaiming their everyday lives with more ease, confidence, and freedom from painkillers. This impact shows what is possible — and reminds us how many women are still in need of better, gentler solutions.

Now, menstruflow is taking the next step and expanding to Indonesia. With millions of women affected by period pain every month, our mission continues beyond borders: to make modern, medication-free pain relief accessible and to break the silence around menstrual health.

menstruflow Indonesia is led by Aiya as CEO, who is responsible for the Indonesian market and drives market development, operations, and strategic growth. With empathy, cultural understanding, and a clear vision, she ensures that menstruflow’s mission is translated thoughtfully and effectively for women in Indonesia. From Germany to Indonesia, one belief guides us: no woman should have to put her life on hold because of period pain. 💜

A word from Dr. med. Ulrike Lange

Every person who menstruates knows period pain — but most don’t know how to treat it other than with painkillers or hormones. In January 2022, I was asked to contribute my professional opinion as a gynaecologist to the development of a TENS device for period pain. I was familiar with TENS technology from other medical fields, but its use for period pain was new to me as well.

As our environmental and body awareness grows, we all look for more natural approaches and methods — and we often stumble across contradictory or even incorrect information online. Especially now, as young women and other people who menstruate increasingly reconnect with natural body states and question traditional approaches, it’s more important than ever to offer reliable, science-based information. At menstruflow, I want to provide clear, accessible information, foster exchange, and help spread a non-pharmacological method for pain relief — one without medication and with no known long-term side effects.
