The homeopathic medicine, Oleander 4X HPUS is indicated for temporary relief of symptoms associated with flu, such as muscle or body aches, headaches, chills and fever, cough, and congestion. The primary purpose of this study is to assess the safety of Oleander 4X HPUS in health male and female subjects compared to a placebo. This is a randomized, double blind, placebo-controlled Phase I Proof of Concept clinical trial to evaluate the safety and efficacy of OLEANDER 4X HPUS in Healthy Volunteers. Briefly, 45 Healthy volunteers who meet the eligibility criteria and agree to participation in the study will be placed on 1.0 mL of OLEANDER 4X HPUS, four-to-twelve times per day for seven days. For the pharmacokinetics study (cohorts 4-6), participants will take OLEANDER 4X HPUS at a prescribed dose one time.

The aim of the present study is to evaluate the safety of OLEANDER 4X HPUS. This real-world cohort provides a unique opportunity to study this medicine. This protocol outlines a study involving Healthy volunteers. Up to 45 volunteers will be recruited in specific health systems in the USA.

Second ARM, sub-study: As a second arm of this study, a random double blind, placebo-controlled pharmacokinetics study in healthy volunteers. Briefly, 15 healthy volunteers who meet the same eligibility criteria and agree to participation in the study will be placed on one, two, or 4 doses (1 mL per dose) of OLEANDER 4X HPUS one time.

This is effectively three ascending doses in 4 subjects on OLEANDER 4X HPUS, compared to the placebo (1 subject).
