About

Endometriosis is a benign disease that affects 6-10% of women of reproductive age. The wide range of symptoms observed in patients with endometriosis is due to implantation of endometrial tissue outside the uterine cavity. This ectopic endometrium is subjected to cyclic changes similar to that of eutopic endometrium. Typically, ectopic lesions are found in the pelvis, notably on the ovaries in the form of cysts (endometriomas), as well as the rectouterine and vesicouterine pouch. Lesions have also been described in other parts of the abdomen and in other locations outside the abdominal cavity.

Although endometriosis has also been described in asymptomatic patients, possible symptoms range from mild to severe pain presenting itself as dysmenorrhea, dyspareunia, or dyschezia, or as infertility. Since the clinical picture varies, the treatment of this disease has become quite personalized. Many studies conducted over the past several years have presented different treatment options for the symptoms caused by endometriosis.

Turmeric, which is won from the rootstalks of Curcuma longa, has more than 300 biologically active elements. One of the three main curcuminoids that are derived from turmeric, is curcumin. Several in-vitro and animal studies have described anti-oxidant, anti-inflammatory and anti-angiogenic effects of curcumin.

The main objective for the treatment of endometriosis patients is symptom relief. Treatment options include analgesic therapies, hormonal therapies, laparoscopic surgery or a combination of these. For patients who refuse hormonal therapies however, conservative treatment options are limited.

Curcuma is a substance that has been in use for centuries, especially in ayurvedic and Traditional Chinese Medicine for the treatment of various symptoms, notably for pain alleviation in inflammatory illnesses. Several recently published studies have shown very promising results of Flexofytol for pain alleviation in patients with osteoarthritis, due to its anti-inflammatory and anti-oxidant properties. Due to these properties of curcuma, we aim to analyse if curcuma capsules, sold by the pharmaceutical company Tilman under the name Flexofytol®, can be used to alleviate symptoms in patients suffering from endometriosis.
