Our Research Summary

Tikun Olam for us is bringing a cure and relief to patients. Research and development are integral to fulfilling our vision. 

Alongside outstanding results and success of treatment, we work and dedicate a great deal of time and effort in order to examine the efficiency and safety of our products; through constant follow-up with patients, laboratory studies, both invitro and in-vivo, retrospective studies, surveys and clinical interventional research (as detailed below).

After treating approximately 20,000 patients, we're now holding the most extensive patient treatment database in the field of medical cannabis anywhere in the world.

 Our proprietary strains and products are examined and distributed as treatment for various diseases and symptoms.

We initiate and sustain partnerships and industrial relations with physicians, scientists and heads of departments of leading medical institutions.

Our chief scientist is Professor Zvi Bentwich - a leading AIDS researcher, chairman of Physicians for Human Rights, and one of the first doctors to treat with medical cannabis in Israel.

CLINICAL STUDIES IN PROGRESS

1.The Effects of Cannabis on Colitis:

Clinical research comparing a group of patients who will be given “Erez” strain cannabis cigarettes (0.5 grams per cigarette) and a group of patients who will be given placebo cigarettes (a total of two cigarettes per day) for a period of eight weeks, during which the effect of the substance on blood inflammation indices, life quality, medicine consumption, and adverse side effects etc., will be monitored.

LABORATORY RESEARCH IN PROGRESS

1. The Anti-Inflammation and Anti-Pain Properties of Cannabis Extracts:

Laboratory research study that was conducted on rodents which examines the effect of extractions of the main strains developed by Tikun Olam on inflammation and pain, in comparison with placebo and isolated CBD.

Head Researcher: Prof. Ruth Gallily

Hospital: Hadassah University Hospital-Ein Kerem, Jerusalem, Israel

 

2.  The Effects of Cannabis on Cancer:

A comprehensive research study is being conducted that compares the effect of extracts from two different strains (one with rich in CBD with very little THC (Avidekel) and one with an equal quantity of both substances (Midnight) - approximately 15%), as well as, a placebo treatment and isolated CBD and THC and both combined. The goal is to narrow down the strain which has the most significant impact on different types of tumors and on mice.  The laboratory research being conducted examines the effects of cannabinoids on human brain tumor cells and separately on nude mice with tumors.
