crushed.
The flowers
are large, with yellow or greenish-yellow colour.
The fruit
of the tree (soursop) is large and has a heart-like shape, covered with small
spine-shaped structures.
The pulp
is fleshy, soft and white in colour, with a slightly sour-acid taste and it can
be eaten out-of-hand. The fruit may contain up to 100 black seeds.
In most
tropical regions of the world, where the plant grows, it is often referred as a
miracle tree.
Parts
Used
In
natural medicine practice, all parts of the soursop tree are used as medicine,
including the roots, barks, stems, leaves, fruits and the fruit-seeds.
Each part
of the tree has long been shown to have different therapeutic properties.
Chemical Constituents
Chemical Constituents
Many
scientific analyses have shown that soursop contains many nutrients, including
protein, sugar, fatty acids, dietary fiber, Vitamins C, B1, B2, iron,
magnesium, manganese, potassium chloride.
It also
contains many bioactive compounds and phytochemicals, such as alkaloid,
citric-acid, malic-acid, stearic-acid, stepharine, tannin, vinblastine, etc.
Therapeutic
Properties
Generally,
it is known that soursop has a broad spectrum antimicrobial, antispasmodic,
anti-diabetic, antioxidant, analgesic, anti-aging, anti-inflammatory,
astringent, cardio tonic, diuretic, emetic, galactagogue, immunity boosting,
laxative, liver tonic, sedative and activities.
Besides
these activities, the main interest in this plant is because of its strong
anti-cancer or anti-tumour properties and effects.
Medicinal
Uses
Cancer and Preventive Agent
Cancer and Preventive Agent
Various
parts of the plant- leaves, stems, fruits and seeds- have been shown to contain
phytochemicals, which are cytotoxic against various types of cancer cells,
including colon, breast, ovarian, uterine, prostate, lung, pancreatic, anal,
kidney, liver, lung and skin cancers.
Soursop
fruit or the fruit juice can be taken to prevent or treat cancer.
The fresh
leaves and stems of the plant can also be used for the same purpose.
In these
cases, about one handful of the fresh leaves and stems of soursop is cut into
pieces and boiled in 1 (One) litre water until the water is reduced to half.
This is then strained and up to100 ml is taken orally morning and night.
The
decoction can be sweetened with pure honey.
Soursop
has been proven to be a miraculous natural cancer cell killer and it is said to
be 10,000 times stronger than most chemotherapy drugs.
A recent
study conducted at Catholic University of South Korea shows that one chemical
(acetogenins) present in soursop was found to selectively kill colon cancer
cells at10, 000 times the potency more than the commonly used Adriamycin (a
chemotherapy drug).
Unlike
chemotherapy, which indiscriminately destroys both cancerous and normal cells,
the compound extracted from the soursop selectively kills only cancer cells
without harming the healthy and normal ones.
