Apple Polyphenol:toxicology and safety.:
Safety and Acute toxicity:
General Safety Status:Apple polyphenol extracts are listed ("apple essence, natural") in the FDA's approved additive/GRAS (Generally Recognized As Safe) database.Researchers found that apple polyphenol extracts are safe, even at concentrations 200 times the recommended human dosage.
Acute toxicity(LD50):Procyanidin B-2 [epicatechin-(4beta --> 8)-epicatechin]
LD50-Lethal dose,50 percent kill.Rat.Subcutaneous.2000 mg/kg. (subcutaneous injection)
Primary irritation tests using rabbits indicated that procyanidin B-2 containing preparation shows no primary irritation. In the guinea pig maximization test, there was no evidence of sensitization to procyanidin B-2.In primary ocular irritation tests using rabbits, procyanidin B-2 containing preparation and vehicle showed slight irritation of conjunctivae which is assumed to be caused by ethanol. It is suggested that topical procyanidin B-2 is safe and acceptable from the series of toxicological tests.

Longterm Use:Apple polyphenol extract has strong antioxidant activity and various physiological functions, and is used as a food additive and nutritional supplements. Here, we tested the consumption safety of Applephenon, which is a polyphenol extract produced from unripe apples. The Ames test without S9 mixture revealed that Applephenon, had slight mutagenicity at a high concentration of 2500 microg/plate; however, both chromosomal aberration test and the micronucleus test found no significant mutagenicity. Furthermore, an acute oral-toxicity test, and a 90-day subchronic-toxicity test showed no significant hematological, clinical, chemical, histopathological, or urinary effects at a dose of 2000 mg/kg. These results confirm that Applephenon is safe and no toxic at average dietary level.

Toxicological studies on procyanidin B-2 for external application as a hair growing agent.:
Procyanidin B-2 [epicatechin-(4beta --> 8)-epicatechin] is one of condensed tannin that exists widely in plants. We have reported previously that procyanidin B-2 possesses hair epithelial cell growth-promoting activity and stimulates anagen induction in hair cycle progression.
To evaluate the safety of topical procyanidin B-2 as a hair growing agent, we examined the mutagenicity, acute subcutaneous injection, primary irritation, skin sensitization, and eye irritation of this compound. Mutagenicity tests using bacteria showed procyanidin B-2 to be non-mutagenic. Chromosomal aberration tests using CHL cells indicated that procyanidin B-2 caused polyploidy but no structural aberrations. In micronucleus tests for mutagenicity using mice, procyanidin B-2 was negative.
Acute subcutaneous injection study using rats revealed no symptoms of significant injury. The lethal dose of procyanidin B-2 is greater than 2000 mg/kg (subcutaneous injection). Primary irritation tests using rabbits indicated that procyanidin B-2 containing preparation shows no primary irritation. In the guinea pig maximization test, there was no evidence of sensitization to procyanidin B-2.
In primary ocular irritation tests using rabbits, procyanidin B-2 containing preparation and vehicle showed slight irritation of conjunctivae which is assumed to be caused by ethanol. It is suggested that topical procyanidin B-2 is safe and acceptable from the series of toxicological tests.
