  Introduction Top

Herbal formulations, which have attained widespread acceptability as therapeutic agents in India, include lipid-lowering, antidiabetic, hepatoprotective, nootropic, and immunomodulatory agents.[1],[2],[3] Cholewin Plus tablet is a polyherbal lipid-lowering formulation containing 11 ingredients of herbal origin. It is the best polyherbal medicine for cholesterol formulated using medicinal plants as recommended by Ayurveda. It is designed to maintain cardiac function as well as to promote hypolipidemia to optimize cardiac health. It works to protect the heart and to strengthen the heart muscles. It regulates cholesterol and triglyceride levels and is also helpful to stop coronary artery blockages. The key ingredients and their roles in the tablet are as follows.

Arjun: Arjun (Terminalia arjuna Rob) is a cardioprotective herb. It prevents oxidative damage to the heart and stabilizes blood pressure.[4]

Guggul and Katuki: Research shows that Guggul (Balsamodendron mukul Hook. ex Stocks) and Katuki (Picrorhiza kurroa Royle ex Benth.) prevent liver from releasing excessive amounts of low-density lipoprotein (LDL) cholesterol into the bloodstream.[5]

Kachnar, Methi, and Taj: Kachnar (Bauhinia variegata L. Benth), Methi (Trigonella foenum-graecum L.), and Taj (Cinnamomum cassia (L.) J. Presi) are useful to maintain healthy blood flow and quality, and they also help in keeping healthy cholesterol levels.[5],[6],[7]

Lashuna: Lashuna (Allium sativum L.) has fibrinolytic, antithrombotic, and anti-hyperlipidemic actions.[11]

In this study, the acute toxicity of Cholewin Plus tablet, a polyherbal formulation, was investigated to assess its safety and tolerability profile in short-term treatment.

  Materials and Methods Top


The supplier provided the test container containing a medicinal herb identified as Cholewin Plus tablet. The herbal remedy, Cholewin Plus tablet, was manufactured by Gayatri Ayupharma Pvt. Ltd., 234/2/2, Patel Estate, Nikol Road, Ahmedabad, Gujarat, India. The test substance was stored according to the manufacturer’s storage condition in a cool and dark place.

Experimental Animals

Adult healthy Wistar albino rats, weighing between 130 and 170g, were obtained from the animal house of the Central Preclinical Research Facility, Datta Meghe Institute of Medical Sciences, Wardha, Maharashtra, India. Nulliparous nonpregnant female rats were selected for acute toxicity study. The animals were housed in 37cm × 23cm × 16cm polypropylene cages with five rats per cage and were maintained at a constant temperature on a standard 12:12 light/dark cycle. Food and water were provided ad libitum. They were allowed to acclimatize for 7 days to the laboratory conditions before the experiment.[13],[14] The experiment was conducted according to the ethical norms approved by Institutional Animal Ethics Committee (Registration No. 571/02/a/CPCSEA), Central Preclinical Research Facility, Datta Meghe Institute of Medical Sciences.

Acute Toxicity Study

Female Wistar albino rats, weighing between 130 and 170g, maintained under standard laboratory conditions were used for the acute toxicity test according to the Organisation for Economic Co-operation and Development (OECD) Guidelines 420.[8] A total of 20 female rats were selected for the study and were divided into four groups having five animals in each group. Animals were kept overnight fasting prior to drug administration by oral gavage. After administration of drug, sample food was provided after 3–4h. All animals were observed individually at least once for the first 30min after dosing and thereafter every 1h for the next 4h. Observation was done daily for the next 14 days every 24h. Daily observation on the changes in skin and fur, eyes and mucous membrane, respiratory rates, autonomic effects such as salivation, lacrimation, perspiration, piloerection, urinary incontinence and defection, and the effects on the central nervous system such as drowsiness, tremors, and convulsions were noted.[8],[9],[10]

Experimental Design

Preparation of test substance

The contents of Cholewin Plus film-coated tablet were insoluble in water. Suspension of the test substance was prepared by triturating the tablet and was suspended in 1% gum acacia solution as a suspending agent and 0.1% Tween 80 as a wetting agent.[12] The suspension was then stored at 4°C for up to 24h. All other chemicals and solvents used in this study were of analytical grade.

Dosage of test substance on animals

Single-dose toxicity study was performed according to OECD Guidelines 420.[8] In order to study any possible toxic effect, four groups of rats (all female) were used in this experiment. The acute toxicity of Cholewin Plus tablet was studied at different dose concentrations. Group I was administered a mixture of 1% gum acacia and 0.1% Tween 80. Groups II, III, and IV were administered test drug suspension at a dose of 5, 300, and 2000 mg/kg, respectively. The maximum volume of gum acacia suspension was not more than 2mL/100g body weight. Animals fasted prior to conducting the experiment only of food but not of water, which was withheld overnight. Following 24h of fasting, the animals were weighed and the test substance was administered. After the test substance was administered, food was withheld for further 2–4h.[13]

Cage Side Observation and Body Weight Measurement

Animals were observed individually after drug administration and special attention was given during the first 4h and every 12h daily thereafter, for a total of 14 days. All observations were systematically recorded, with individual records being maintained for each animal. Cage side observation included evaluation of skin and fur, eyes, respiratory effects; autonomic effects such as salivation, diarrhea, and urination; and the central nerve effects including tremors and convulsions; changes in the level of activity; gait and posture; reactivity to handling or sensory stimuli; and altered strength.[14],[15] Individual body weight was measured and recorded prior to the administration of the test drug. After 2 weeks, the change in body weight of animals was calculated and recorded.[13]

Food and Water Consumption

The amount of food and water consumed was measured daily from the quantity of food and water supplied and the amount remaining after 24h for 2 weeks of the study period.[13],[14]

Body Weight

The change in body weight was recorded on day 1 before dosing as well as on day 8 and day 15 after dosing that is weekly basis.[13],[14],[15]


During the study period, all animals were observed daily for any mortality. If any dead animal was found, histopathology was performed of that animal and it was observed for any abnormal sign on measure organs such as kidney, liver, and heart. After completion of the study, all animals were killed using anesthesia, and histopathology was performed and the results were recorded.[16],[17]

  Results Top

Acute Toxicity Study

No mortality and morbidity or any toxicity or any sign of behavioral changes were observed throughout the 14-day period after single oral administration of Cholewin Plus tablet suspension up to the dose of 2000 mg/kg body weight. The morphological characteristics such as fur, skin, eyes, and nose appeared normal. During observation no tremors, convulsion, salivation, diarrhea, lethargy, or unusual behaviors such as self-mutilation and walking backward were observed; gait and posture, grip strength, and sensory stimuli all were found to be normal. Observations were recorded and were reported in [Table 1].

No abnormalities were detected in pathological examinations of the tissues during microscopic examination of internal organs in comparative histology of tissues of control and test animals. Cholewin Plus tablet does not affect the histology of vital organs, namely, lungs, heart, spleen, liver, and kidneys.

  Discussion Top

Nowadays a number of polyherbal-based formulations are used abundantly worldwide compared to allopathic medicines for the treatment of different types of ailments.[18] In India, different types of Ayurveda-based herbal formulations are used for the treatment of lipid disorder as well as to maintain cardiac function.[19] The test formulation was the mixture of this herbal plant formulated in the form of a tablet. These tablets help maintain healthy cholesterol level, increase good cholesterol level, and prevent coronary artery diseases.[20],[21] In this study, acute toxicity of herbal product was analyzed in female Wistar rats as a single-dose study. The acute toxicity study was conducted for 14 days at the dose of 5, 300, and 2000 mg/kg/day administered daily in all groups. The results showed that there was no morbidity and mortality. This proves that the drug could be safely administered for acute treatments up to a maximum dose level of 2000 mg/kg/day for the oral route. The change in body weight has been used as an indicator of the adverse effect of test formulation. During the experimental period, no remarkable changes were observed in animal behavior, body weight, and organ weight at all dose levels in treated rats as compared to a controlled group. It can be inferred that test substance is nontoxic at the dose administered. The analysis of animals’ blood parameters can be used for risk evaluation in humans as a change in the hematological system has a higher predictive value for human toxicity of test compound. In this study, all hematological parameters that were observed showed normal value for the animal blood sample. So we can predict that this herbal formulation is safe for humans also.

  Conclusion Top

The result strongly supports that the herbal Cholewin Plus tablet formulation is safe and well tolerated at the tested oral doses of 5, 300, and 2000 mg/kg/day for 14 days as no deleterious changes were observed in animal macroparameters, behavior and habits, hematology, and histopathological parameters.
