APEC Youth Scientist Journal Vol.6 / No.2 VIABILITY OF HEART VEIN OPENING DRINK ∗ 1 Tay Jing Sheng Sekolah Menengah Kebangsaan Lutong, Jalan Pantai Lutong, 98000 Miri, Sarawak, Malaysia ABSTRACT In this research paper, it will identify whether the Heart Vein Opening Drink, a solution to cardiovascular diseases that is widely spreaded among the community, have the cardioprotective properties as the community said. Cardiovascular diseases is now one of the most threatening diseases to mankind, thus if there is a prevention or cure to it, research should be done to identify it and to find the reason behind this. However, the results in this research are conflicting and demands for further development of research. 1. INTRODUCTION If you search the title above online you will be able to find a lot of website introducing this drink and also the ingredients for making the drink. This is how it is prepared: a) Ingredients: 1 cup of Lemon juice,1 cup of Ginger juice,1 cup of Garlic juice and 1 cup of Apple cider vinegar b) Mix all above and simmer in low heat for about 60 minutes or till solution reduces to 3 cups. c) Remove solution to cool, then mix 3 cups of natural honey and store it in a jar. According to the article “For Your Heart Vein Opening”, by drinking one tablespoon of this drink daily before breakfast, vein’s blockage will open in most cases. The article also gives an extract from Mufti Mohammed Kantharv’s post as evidence. Here’s the text of the extract: ∗ Correspondence to : Tay Jing Sheng ([email protected]) - 231 - APEC Youth Scientist Journal Vol.6 / No.2 “Please Wait…………………….. Before you undergo Angiography or Bypass treatment, you must try with confidence this remedy. Insha Allah, you will be cured. On the 18th April last year, I had to go to Sahiwaal(Pakistan) from the UK to attend the annual Khatme-e-Nabuwat conference. The day before I suffered acute pain at the place of my heart and thereafter, experienced uncomforting which continued for quite some time. I then met in Pakistan Hazrat Moulana Bashir Ahmed Usmani Sahib and disclosed to him, that when the doctors performed Angiography on me, they advised Bypass as they discovered 3 of my arteries were blocked and given a date to operate after a month. During this period, a Hakim prescribed the remedy below which I consumed exactly for a month. A day before my bypass operation, I arrived at the Cardiology Hospital in Lahore (Pakistan) and deposited Pak Rs. 225,000.00 towards expenses for my Bypass surgery. After taking a close look at these results and my previous results, the Doctors then asked me if I took any medication after the previous tests were carried out. I told them of Hakim Sahebs prescribed remedy. The panel of Doctors, surprised by the results, then informed me that according to the latest reports all 3 arteries were open and functioning normally and that surgery was not required. I was refunded my deposit and told to go home. Hazrat Moulana Bashir Ahmed Usmani Saheb himself, prepared this medicine for me and also told me of it’s ingredients and how it is prepared which is as follows: 1 Cup Fresh Lemon Juice 1 Cup Fresh Ginger Juice 1 Cup Fresh Garlic Juice 1 Cup Apple Cider Vinegar 3 Cups Honey Mix all the juices & vinegar and boil very slowly for about half an hour until about 1 cup of contents evaporate and 3 cups remain. After it cools down, mix properly with the 3 cups of honey. Fill contents in a clean Jar and take 3 teaspoons on an empty stomach every morning. Insha Allah you will be cured.”(From Mufti Mohammed Kantharvi. London UK) However, the effects of the drink to health are not yet been proven by scientist. The question is: Do this drink really helps out in opening vein’s blockage? - 232 - APEC Youth Scientist Journal Vol.6 / No.2 1.1.Cardiovascular Diseases Cardiovascular disease (also called heart disease) is a class of diseases that involve the heart, the blood vessels (arteries, capillaries, and veins) or both. Cardiovascular disease refers to any disease that affects the cardiovascular system, principally cardiac disease, vascular diseases of the brain and kidney, and peripheral arterial disease. The causes of cardiovascular disease are diverse but atherosclerosis and/or hypertension are the most common. Additionally, with aging come a number of physiological and morphological changes that alter cardiovascular function and lead to subsequently increased risk of cardiovascular disease, even in healthy asymptomatic individuals. Cardiovascular disease is the leading cause of deaths worldwide, though since the 1970s, cardiovascular mortality rates have declined in many high-income countries. At the same time, cardiovascular deaths and disease have increased at a fast rate in low and middle income countries. Although cardiovascular disease usually affects older adults, the antecedents of cardiovascular disease, notably atherosclerosis, begin in early life, making primary prevention efforts necessary from childhood. There is therefore increased emphasis on preventing atherosclerosis by modifying risk factors, such as healthy eating, exercise, and avoidance of smoking tobacco. Currently practiced measures to prevent cardiovascular disease include: - A low-fat, high-fiber diet including whole grains and plenty of fresh fruit and vegetables (at least five portions a day) - Tobacco cessation and avoidance of second-hand smoke; - Limit alcohol consumption to the recommended daily limits; consumption of 1-2 standard alcoholic drinks per day may reduce risk by 30% However excessive alcohol intake increases the risk of cardiovascular disease. - Lower blood pressures, if elevated; - Decrease body fat (BMI) if overweight or obese; - Increase daily activity to 30 minutes of vigorous exercise per day at least five times per week; - Reduce sugar consumptions; - Decrease psychosocial stress. Stress however plays a relatively minor role in hypertension. Specific relaxation therapies are not supported by the evidence. For adults without a known diagnosis of hypertension, diabetes, hyperlipidemia, or cardiovascular disease, routine counseling to advise them to improve their diet and increase - 233 - APEC Youth Scientist Journal Vol.6 / No.2 their physical activity has not been found to significantly alter behavior, and thus is not recommended. 1.2.Purpose of the studies a. To identify the nutrients of the ingredients in making the Heart Vein Opening Drink that is cardioprotective. b. To test the presence of the nutrients in the Heart Vein Opening Drink in order to identify whether the nutrients is lost during the process of producing the drink. c. To identify the effect of the drink in opening vein’s blockage. 2. METERIALS 2.1.Fresh Lemon Juice The lemon (Citrus × limon) is a small evergreen tree native to Asia, and the tree's ellipsoidal yellow fruit. The fruit is used for culinary and non-culinary purposes throughout the world, primarily for its juice, though the pulp and rind (zest) are also used in cooking and baking. The juice of the lemon is about 5% to 6% citric acid, which gives lemons a sour taste. The distinctive sour taste of lemon juice makes it a key ingredient in drinks and foods such as lemonade. 2.1.1.

Lemon and Cardiovascular diseases Lemons, like other fellow citrus fruits, are an excellent source of vitamin C (ascorbic acid); provides about 88% of daily recommended intake. Ascorbic acid is a powerful water soluble natural anti-oxidant. Moderately higher blood levels of vitamin C measured in healthy persons have been found to be prospectively correlated with decreased risk of cardiovascular disease and ischaemic heart disease, and an increase life expectancy. In vitro experiments revealed that both citric acid and L-malic acid significantly reduced LDH release, decreased apoptotic rate, downregulated the expression of cleaved caspase-3, and upregulated the expression of phosphorylated Akt in primary neonatal rat cardiomyocytes subjected to hypoxia/reoxygenation injury. These results suggest that both citric acid and Lmalic acid have protective effects on myocardial ischemia/reperfusion injury, whilst juice of lemon contains rich amount of this cardioprotective citric acid, which is about is about 5% to 6%. Furthermore, citrus fruits offer natural protection for the heart. This has been demonstrated by a group of researchers at the department of Pharmacy at the University of Pisa, who recently published results of their work in the scientific journal "Biomedical Pharmacology". These Pisan researchers have shown that naringenin – a flavonoid which citrus fruits such as oranges, lemons and grapefruits are particularly rich in – has (in addition - 235 - APEC Youth Scientist Journal Vol.6 / No.2 to its anti-oxidant properties) important cardio-protective properties against ischemic damage by a specific interaction with a protein (in particular an ion channel) located at the level of the cardiac mitochondria. In addition, lemon contains 2.8g of dietary fiber per 100g, and dietary fiber is part of the National Cholesterol Education Program’s recommendation for maintaining healthy cholesterol levels. In clinical trials to date, fiber sources were shown to significantly reduce blood cholesterol levels, an important factor for general cardiovascular health, and to lower risk of onset for some types of cancer. 2.2.Fresh Ginger Juice Ginger or ginger root is the rhizome of the plant Zingiber officinale, consumed as a delicacy, medicine, or spice. Young ginger rhizomes are juicy and fleshy with a very mild taste. They are often pickled in vinegar or sherry as a snack or just cooked as an ingredient in many dishes. They can also be steeped in boiling water to make ginger tea, to which honey is often added; sliced orange or lemon fruit may also be added. Ginger can also be made into candy, or ginger wine which has been made commercially since 1740. Mature ginger rhizomes are fibrous and nearly dry. The juice from old ginger roots is extremely potent and is often used as a spice in Indian recipes, and is a quintessential ingredient of Chinese, Korean, Japanese and many South Asian cuisines for flavoring dishes such as seafood or goat meat and vegetarian cuisine. 2.2.1.

Ginger and Cardiovascular diseases Native to Asia, ginger is a common cooking spice. The University of Maryland Medical Center cites several preliminary studies that suggest ginger may lower cholesterol and prevent blood from clotting. Stopping your blood from clotting can help people with heart disease, where blood vessels become clogged and lead to heart attack or stroke. High cholesterol can also lead to clogged arteries when the cholesterol builds up on the artery walls. Ginger may also help to lower blood pressure, another indicator of heart disease. A study published in 2005 in the “Journal of Cardiovascular Pharmacology” found that ginger lowered blood pressure in controlled experimental conditions. Researchers investigated the cardiovascular effects of ginger on the blood pressure of different animals. Using crude extract of fresh ginger injected intravenously in rats, researchers found a dose-dependent fall in blood pressure. Further experiments in this research suggest that the blood-pressurelowering effect of ginger is due to the blockage of voltage-dependent calcium channels. However, researchers did not examine the effects of ginger on the blood pressure of humans. Israeli researchers have found that ginger extract can have dramatic effects of cardiovascular health, including preventing atherosclerosis, lowering cholesterol levels, and preventing the oxidation of low density lipoprotein (LDL). The researchers note that oxidative damage of LDL is thought to play a key role in the development of atherosclerosis and that consumption of nutrients rich in phenolic antioxidants (gingers) has been shown to be associated with slowing down the development of atherosclerosis. Ginger is an amazing herb with many healing powers, helping with; appetite, arthritis, cellulite, pneumonia, colds, seas sickness, nausea, preventing blood clots and increasing circulation. While all of these - 237 - APEC Youth Scientist Journal Vol.6 / No.2 benefits of ginger are amazing, the one that is most impressive is its heart health benefits. Ginger is used for blood pressure, cholesterol regulation, increased circulation, and overall heart health. 2.3.Fresh Garlic Juice Allium sativum, commonly known as garlic, is a species in the onion genus, Allium. Garlic is widely used around the world for its pungent flavor as a seasoning or condiment.The garlic plant's bulb is the most commonly used part of the plant. With the exception of the single clove types, garlic bulbs are normally divided into numerous fleshy sections called cloves. Garlic cloves are used for consumption (raw or cooked) or for medicinal purposes. They have a characteristic pungent, spicy flavor that mellows and sweetens considerably with cooking. In the recipe of Heart Vein Opening Drinks, garlic bulb is used as one of the ingredient. 2.3.1. Nutritional Value of Garlic Table 3: Garlic (Allium sativum), Total-ORAC value 5346 µmol TE/100 g.

Garlic and Cardiovascular diseases Several well planned studies have indicated that garlic may have a role in cardioprotection. Garlic has been shown to inhibit cholesterol biosynthesis in hepatocytes and liver homogenates. Beaglehole cites Jain and colleagues' controlled clinical trial in which garlic reduced serum lipid concentrations. In support of these findings Harenberg and colleagues reported that garlic reduced serum cholesterol concentrations by 10% in patients with hyperlipoproteinaemia. Garlic also reduced systolic and diastolic blood pressure in these patients, but platelet aggregation was not affected. Recent data from Ali and Thomson confirmed the serum cholesterol reduction by garlic, and more importantly an 80% reduction in serum thromboxane concentrations. Another important property of garlic that Beaglehole does not mention is its antiplatelet aggregation properties. It has been known for some time that garlic decreases platelet aggregation thus inhibiting some aspects of thrombus formation. Several well conducted studies have confirmed garlic's ability to inhibit platelet aggregation thus reducing the frequency of thrombus formation. Many well planned studies are showing that garlic has cardioprotective properties. Standard solutions of garlic and its extracts are now available, and more basic research and clinical trials are needed to test them. 2.4.Apple Cider Vinegar Apple cider vinegar, otherwise known as cider vinegar or ACV, is a type of vinegar made from cider or apple must and has a pale to medium amber color. Unpasteurized or organic ACV contains mother of vinegar, which has a cobweb-like appearance and can make the vinegar look slightly congealed.ACV is used in salad dressings, marinades, vinaigrettes, food preservatives, and chutneys, among other things. It is made by crushing apples and squeezing out the liquid. Bacteria and Yeast are added to the liquid to start the alcoholic fermentation process, and the sugars are turned into alcohol. In a second fermentation process, - 239 - APEC Youth Scientist Journal Vol.6 / No.2 the alcohol is converted into vinegar by acetic acid-forming bacteria (acetobacter). Acetic acid and malic acid give vinegar its sour taste. 2.4.1. Apple Cider Vinegar and Cardiovascular diseases In general, the present study indicated that consumption of apple cider vinegar can reduce the LDL, triglyceride, and cholesterol levels in patients with hyperlipidemia. Besides, given that hyperlipidemia is a known risk factor for atherosclerosis, apple cider vinegar can be used to prevent and even treat this complication and probably other heart problems. A study by the Central Research Institute at the Mitsukan Group Corporation in Aichi, Japan, found that acetic acid -- a main compound in apple cider vinegar -- could have an antihypertensive effect on blood pressure. After six weeks, systolic blood pressure was reduced by an average of 20 mmHg. However, the study was only performed on spontaneously hypertensive rats, so additional research on human subjects is needed to determine if the acetic acid in vinegar would prove beneficial on hypertensive patients. According to another study by the research group, acetic acid may also help to improve cholesterol levels. Rats were fed a cholesterol-rich diet in conjunction with the acetic acid. When compared to a control group, rats given acetic acid had significantly lower serum cholesterol and triacylglycerol levels than those fed only a cholesterol-rich diet. It appears the main compound in vinegar inhibits lipogenesis, which is the process of turning simple sugars into fat. Both cholesterol and triacylglycerol are forms of fats, or lipids, in the bloodstream. Again, additional research on people is needed to determine if acetic acid can improve cholesterol levels in patients with high cholesterol and triglycerides. 2.5.Honey 2.5.1.

Honey and Cardiovascular Diseases To date, a substantial number of studies have reported the efficacy of flavonoids, found in honey, in heart diseases. Flavonoids reduce the risk of cardiovascular diseases in acute and short-term interventions in healthy volunteers and in risk population groups. Some studies are in favor of beneficial effects of increased intake of honey flavonoids on the cardiovascular system (Hertog et al. 1993, 1995, 1997a; Knekt et al, 1996, 2002; Yochum et al. 1999: Arts et al. 2001), while data from other studies indicate that honey has no effect on heart disease. Results on the effect of honey in heart disease are conflicting (Rimm et al. 1996; Hertog 1997b; Sesso et al. 2003; Lin et al. 2007); therefore, more studies especially on large human population are urgently required. Honey flavonoid decrease the risk of coronary heart disease by the following major actions: (1) improving coronary vasodilation, (2) decreasing the ability of platelets conversion to clot, (3) preventing oxidation of LDLs, (4) increasing high density lipoprotein (HDL), and (5) improving endothelial function. In addition, honey has high levels of antioxidant compounds. These polyphenols may also contribute to stabilization of the atheroma plaque and therefore add to the cardioprotective effects of honey, supporting its cardioprotective properties. A presumption is made that the Heart Vein Opening Drink with the ingredients listed above should have cardioprotective properties like what its ingredients have. 3. EXPERIMENTS Experiments are planned and conducted in order to determine the effects of the Heart Vein Opening Drink in cardiovascular diseases. Due to the restriction of my capabilities to prepare and perform more accurate, precise and detailed experiment, the results may not be confirmed and requires further development. Few simple experiments were planned, with those listed below which are carried out successfully. - 241 - APEC Youth Scientist Journal Vol.6 / No.2 3.1.Chicken blood test Aim: Determining the effects of the Heart Vein Opening Drinks to the prevention of plaque in blood vessels Problem Statement: Does the Heart Vein Opening Drinks help to prevent blockage of blood vessel? Variables Manipulated: Solution added to the chicken blood Responding: Condition of the chicken blood Constant: Surrounding temperature, volume of chicken blood Materials: chicken blood, heart vein opening drink Apparatus: measuring cup, glass cup Assumption made: Chicken blood is similar to the human blood and forms plaque by the same factor Procedure Step 1: 10ml of chicken blood is dropped into a glass cup Step 2: The solution is left for days and any changes per day is observed and recorded Step 3: The experiment is repeated by using solution of chicken blood added with Heart vein opening drink solution. Figure 1: Day 0 (both not coagulate) Figure 2: Day 1 (both not coagulate) - 242 - APEC Youth Scientist Journal Vol.6 / No.2 Figure 3: Day 2 (Chicken blood only; coagulates) Figure 4: Chicken blood with Heart Vein Opening Drink (Not coagulate) 3.2.Human test Aim: Determining the effects of the Heart Vein Opening Drinks to the prevention of plaque in blood vessels Problem Statement: Does the Heart Vein Opening Drinks help to maintain the values of lipids and cardiovascular risks at desirable range? Hypothesis: Heart Vein Opening Drinks can maintain the values of lipids and cardiovascular risks at desirable range Procedure Step 1: A subject is selected to participate in the experiment. Step 2: The health test of the subject is carried out before experiment and the results for section “lipids and cardiovascular risks” are recorded. Step 3: Then, the participants’ lifestyle is remained similarly as usual, only except that they start to have one tablespoon of the Heart Vein Opening Drink daily before breakfast. Step 4: After 4 months, the health test of the subject is carried out again and the results for section “lipids and cardiovascular risks” is recorded. - 243 - APEC Youth Scientist Journal Vol.6 / No.2 Results First Test - 244 - APEC Youth Scientist Journal Vol.6 / No.2 Second Test - 245 - APEC Youth Scientist Journal Vol.6 / No.2 Comparison Description Cholesterol, Total HDL-Chol.

Heart Vein Opening Drinks shows no effects on preventing cardiovascular diseases. Hypothesis is not accepted 4. CONCLUSION The results of the two experiments conducted show conflicting results on the cardioprotective properties of the Heart Vein Opening Drinks. More experiments that are more accurate, more precise, more detailed and more controlled have to be carried out in the future to make the results confirmative. As a conclution, the research requires further development but by research done so far now, the Heart Vein Opening Drinks is not practically proven its with prevention and cure of cardiovascular diseases. 5.
