What Components Of Guanabana (Soursop) Work Against Cancer?
Graviola, guanabana, or soursop whatever you call it, is almost the same. This fruit is prevalent in the rainforests of Africa, South America, and Southeast Asia.
Since long alternative practitioners are using soursop fruit and Graviola tree leaves to cure stomach ailments, fever, hypertension, rheumatism, and as a sedative.
The fruit, bark, and the leaves of soursop fruit have loads of anticancer, antioxidant, anti-inflammatory, and antimicrobial properties. It is because of these properties it can cure multiple health issues.
In one of the phytochemical study, it was found that Guanabana is rich in acetogens. Acetogen is a class of bioactive polyketide-derived constituents which are very powerful anti-cancer agents. This class also has anti-inflammatory and antioxidative properties.
The Acetogen are selectively cytotoxic against the neoplastic cells. They have the ability to kill cancer cells only and also prevent their multiplication.2
The Gravilo seeds, fruit, leaves, and bark have dozens of these compounds. In a study it was found there are more than 50 different type of Acetogens in Guanabana fruit and seed.3
Further, the mechanism of action of acetogens against cancer cells is brought about by blocking the nutrition of the cancer cells only.
The phytochemicals work to inhibit the complex I that is NADH ubiqunoa oxidoreductase. When this chemical form of energy is blocked, the cells are short of ATP. In absence of ATP, the cancer cells are unable to get energy and food for their survival and eventually they die.
Guanabana(soursop) can prevent a variety of cancer like colon cancer, prostate cancer, breast cancer, pancreatic cancer, and skin cancer.4
How To Use Soursop For Cancer
Cancer is a deadly disease that can be cured with conventional treatment methods.Guanabana alone cannot cure cancer, but it can surely help to stop its progression and increase the efficacy of the cancer treatment.
The leaves and the seed of soursop have the highest amount of anti-cancer properties.5
However, the seeds are not recommended as they might contain toxic compounds so you should always consume the leaves. Prefer drinking soursop tea prepared with the leaves. Drink two to three cups of soursop tea daily for good results.
Additionally, prefer consuming the fruit also for added benefits. Make sure not to consume too much instead just keep the amount to moderate levels.
Scientific Study To Prove The Effectiveness Of Soursop Against Cancer
The scientific name of Soursop is Annona muricata. There are a number of scientific studies performed to evaluate its effectiveness against cancer. A few of the famous studies are listed below:
1. Anti-cancer Properties Of Graviola
This is the most recent study done on the Graviola (Annona muricata). All the aerial parts leaves, bark, stem, fruit, pericarp, roots, and seed were studies in this one.6
Over 212 phytochemical constituents of the plant were accessed. The basis of the study was to evaluate the mechanism of action of action of these constituents on the cancer cells.
Several phytochemical extracts like n-hexane, chloroform, pentane, hexane, ethanol, methanol, and ethyl acetate were checked for their anti-cancer activities.
The outcomes of the study suggested that Acetogenins and other secondary metabolites, including alkaloids present in the soursop plant, can decrease cancer growth.
Overall, the study concluded with a call for action to manufacture Graviola based pharmaceutical and agricultural product to cure deadly health ailments like cancer.
