The tolerability of different cannabinoids given orally to dogs was evaluated in a randomized, non-blinded, negative controlled, parallel design 90-day repeat dose study with a 14-day recovery period. Healthy beagles (16 males and 16 females) were randomized into four treatment groups and treated with either medium chain triglyceride oil as the control or one of the following: broad spectrum cannabidiol, broad spectrum cannabidiol with cannabigerol, or broad spectrum cannabidiol with cannabidiolic acid at 5 mg total cannabinoids/kg body weight/day. Animals were observed daily with detailed clinical examinations conducted weekly.

The results of safety studies performed with Elixinol Hemp Extract, a blend of hemp extract, cannabidiol (CBD) isolate, and copaiba containing approximately 65% total CBD, are described in this paper. In a 15-day range-finding study in rats, there were no effects of treatment with up to 101.4 mg/kg bw/day of the extract by gavage on any safety parameter measured in the study, with the exception that centrilobular hepatocellular hypertrophy occurred in all treatment groups, which correlated with increases in absolute liver weight in high-dose females and liver to terminal body weight ratio in mid-dose and high-dose females.

Article Synopsis
  • - HempChoice® Hemp Oil Extract is a hemp-derived product mostly containing 55-75% cannabidiol (CBD) along with other cannabinoids and terpenes, with no significant safety concerns shown in multiple studies.
  • - Safety studies, including a 90-day trial, revealed that the extract was well tolerated with no serious side effects, and any minor changes observed were considered temporary and reversible.
  • - The extract's no observed adverse effect level (NOAEL) was established at 185.90 mg/kg body weight/day based on testing in Sprague-Dawley rats, indicating a safe threshold for consumption.

Bioactive phytochemicals such as salidroside have been studied to understand the beneficial effects of , an herbaceous plant used in traditional medicine to increase energy and treat a variety of health issues. However, Rhodiola plants are often slow-growing, and many are endangered in their native habitats. Thus, there is a need for safe, alternative supplies of key phytochemicals from Rhodiola.

VOHO Hemp Oil (Verdant Nature LLC (in collaboration with HempFusion)) is an extract of the aerial parts of hemp (Cannabis sativa L) manufactured using a supercritical CO2 extraction process. The results of four safety studies are reported here including a bacterial reverse mutation assay, an in vivo mammalian micronucleus study, a maximum tolerated dose study in rats and a 90-day repeat dose subchronic toxicity study in rats. VOHO Hemp oil can contain up to 30% phytocannabinoids and less than 0.

Article Synopsis
  • The study evaluated the effects of aluminum citrate on Sprague-Dawley rat offspring using a double-blind, vehicle-controlled design and multiple dose levels (30, 100, 300 mg Al/kg bw/day).
  • The most significant findings included renal pathology, particularly in male pups, with higher mortality in the high-dose group leading to euthanization at day 89.
  • Despite some dose-response relationships in neuromuscular measurements, most behavioral and cognitive assessments did not show consistent treatment-related effects, and any observed brain lesions were attributed to aging rather than aluminum exposure.

Cattle exposed to low doses of an Alberta crude oil, Pembina Cardium crude oil (PCCO), or a winter diesel oil no. 2 (WDO-2) were assessed for their biochemical activities in polymorphonuclear leukocyte (PMNL) cells (mainly neutrophils). The study used a randomized block design containing five treatment groups (8 animals/group).
