Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is performed to consider the safety and healing ability of diosmin in patients with systemic sclerosis (scleroderma) and open sores on their fingers (digital ulcers). Two (2) out of three (3) participants will receive active product. The participants will have four (4) visits over eight (8) weeks. Physical exams and photos will be performed. A variety of questions will be asked describing level of pain and lifestyle changes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is performed to consider the safety and healing ability of diosmin in patients with systemic sclerosis (scleroderma) and open sores on their fingers (digital ulcers). The study will include 21-45 participants randomly given active product or inactive product (placebo). Two (2) out of every three (3) participants enrolled will receive active product. The participants will have four (4) visits over eight (8) weeks. At each visit physical exams and photos will be performed. Each person will also be asked a variety of questions describing level of pain and any changes to their lifestyle.
