To demonstrate the clinical efficacy of the combination of Aesculus hippocastanum, Polygonum acre, Smilax Pepyracea, and rutin in tablets in improving local symptoms (bleeding, pain, thrombosis, perianal dermatitis, hemorrhoidal nipple prolapse) assessed using a 100mm visual scale (VAS) over 60 days among adult patients with grade 1, 2 or 3 hemorrhoidal disease.
Hemorrhoidal disease (HD) is the most common proctological condition, with an up to 86% prevalence (asymptomatic individuals underestimated). It is expected that 5% of the population might have at least one episode of HD during their lifetime, most individuals amenable to medical therapy but 10 to 20% of them requiring surgical intervention. HD has an occurrence peak between the 5th and 7th decades of life. Haemorrhoids can be defined as varicose dilatation of the submucosal anorectal veins due to persistently elevated venous pressure in the hemorrhoidal plexus, that is, they develop when the venous drainage of the anus and rectum is altered, causing dilatation of the venous plexus and connective tissue, creating an overgrowth of the anal mucosa of the rectal wall. The term HD is used when haemorrhoids cause symptoms. Aesculus hippocastanum (horse chestnut), rutin, Smilax papyracea (sarsaparilla), Polygonum acre (dotted smartweed) combination is commonly used to control chronic venous insufficiency (CVI) manifestations. Assuming pathophysiology of HD and CVI are similar, the investigators hypothesized the above combination could be also useful in the management of the former condition.
Fundação Educacional Serra dos Órgãos is the lead sponsor of 10 studies on the registry; none are open to participants now.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Hemorrhoidal Disease Symptom Score (HDSS) (adapted)
4 questions: 1. How often do you feel pain because of your hemorrhoids? 2. How often do you experience itching or discomfort in your anus? 3. How often do you bleed when you have a bowel movement? 4. How often do you soil your underwear (anal soil)? Possible answers: * Never * Less than once a month * Less than once a week * 1 to 6 days a week * Every day (always)
Time frame: 2 months
Short Health Scale HD (SHSHD)
1. In your opinion, how severe are your symptoms caused by hemorrhoids? 2. Do your symptoms interfere with your daily activities? 3. Are your symptoms causing you a lot of concern? 4. How is your overall sense of well-being? Possible answers: * 1 * 2 * 3 * 4 * 5
Time frame: 2 months

Effectiveness in hemorrhoidal symptoms
The 100mm visual scale is assessed by the patient between "0" = absence of venous symptoms and "100" = maximum intensity of symptoms. The visual scale is performed by the patient in the presence of the investigator. This visual scale assesses the symptoms of haemorrhoidal disease in a global manner: bleeding, pain, thrombosis, perianal dermatitis (pruritus or anal discomfort), prolapse of the hemorrhoidal nipple, soiling.
Time frame: 3 months
