Island Nest has been used as medicine for a long time.
Literature witnesses the consumption of ISLAND NEST as “bird’s nest soup” by
Chinese populations from almost 1200 years ago.
Traditional Chinese Medicine recommends ISLAND NEST as one
of the most important bioproducts with health improving effects such as growth
promoting, anti-aging, immunity boosting, anti-cancer, anti-aging, dissolving
phlegm, immunity-enchancing, alleviating asthma, curing tuberculosis, stomach
ulcers and hematemesis, suppressing cough, improving voice, etc.
The uniqueness of ISLAND NEST in TCM is mainly due to its
dual nature as it is being used as medicine on one hand and food on the other
hand. There has been significant amount of research of ISLAND NEST as medicine,
and some of the findings are discussed in the following sub-sections.
Anticancer Properties
Cancer stands as the second most deadly disease after
cardiovascular diseases. It has created major public health havoc globally and,
therefore, the agents for its treatment have always been in great demands.
Natural products as anticancer agents have always been
appealing to researches owing to their promising effects within large safety
margins. Presently, several natural product-based anticancer agents are used
for treating different cancers. Rashed and Nazaimoon demonstrated the effects
of ISLAND NEST on the proliferation of caco-2 cells by using the MTT assay.
The edibe bird nest samples were collected from the
Department of Wildlife and National Parks, Kuala Lumpur comprising of two
commercial brands and four unprocesed samples. Only 84 and 115% cells were
found to proliferate on treatment with the two commercial ISLAND NEST samples.
However, 91, 35 and 47% cells proliferations, respectively were reported on
treatment with unprocessed ISLAND NEST samples from East Coast, North and South
Zones. These results suggested the anticancer potential of ISLAND NEST.
Complementary and alternative medicine (CAM) defines a group
of medical and health care systems, practices and products, which are not
considered as part of conventional medicine. In Singapore, both cancer patients
from western and eastern cultures were exposed to CAM ranging from health
supplements to Traditional Chinese Medicine (TCM), traditional Malay (Jamu)
medicine and traditional Indian (Ayurvedic) medicine. CAM usage is quite
popular among cancer patients. Dietary changes, health supplements, herbal tea
and birds nest were the main threapeutic ingredients of CAM.
There are documented usage of Complementary and alternative
medicine (CAM) in Singaporean adult cancer patients. An
interviewer-administered questionnaire was completed by 403 adult cancer patients
under treatment at the Ambulatory Treatment Unit of National Cancer Centre
Singapore, among all the patients, 46% testified CAM usage including TCM,
bird’s nest and special diet. 54% respondents updated their oncologists about
CAM usage and interestingly, 66.4% of the oncologists agreed with CAM usage.
The effective working of CAM against cancer was felt by majority of the
patients.
This report indicates the benefits of the the consumption of
Island Nest in cancer patients, however, it is very important for health-care
professionals to be updated with Complementary and alternative medicine (CAM)
research and to actively provide appropriate advise and counselling.
Of course, the studies involving the anticancer evaluation
of Island Nest and its extracts have not been carried out over a large range of
cancer cells. Only one preliminary study was found in the literature. One of
the reasons for the lack of research may be that Island Nest is a rich food
and, therefore, a growth promoter, and it is unlikely to kill cancer cells.
However, this may not be true as well. Therefore, it is important to screen Island
Nest over a range of cancer cell lines before any meaningful conclusion can be
drawn.
Antiviral Properties
Viruses are microscopic infectious agents that replicate
only inside living cells of orther organisms. They infect all life forms
including animals, plants, bacteria and archaea. Viruses exhibit several
structural and biochemical effects on host cells, the cytopathic effects. Most
of the viral infections lead to the lysis of cells, alterations in cell
membranes and ultimately the death of host cells. Cold, influenza, chickenpox,
cold sores, AIDS, avian influenza and SARS, etc. are some of the most common
diseases caused by viral infections.
Influenza is a viral infection caused by influenza virus.
Its symptoms include high fever sore throat, runny nose, muscle pains, headache
coughing and tired feeling Island Nest helps to neutralize influenza virus
infection in MDCK cells and also causes the inhibition of hemmaglutination of
human erythrocytes caused by influenza A viruses.
After hydrolyzation with Pancreatin F, Island Nest inhibits
the infection caused by human, avian, and porcine influenza viruses in a host
range-independent manner. However, Island Nest does not inhibit influenza virus
sialidase, and the active inhibiting ingredient of Island Nest is susceptible
to neuraminidase of influenza virus of all strains.
The Collocalia mucoid is an established substrate for
influenza virus sialidase, wherein the inhibition can be destroyed by
neuraminidase to some extend. Owing to the activites of ISLAND NEST against
influenza viruses, the presence of a mixture of inhibitory substances in ISLAND
NEST was suggested.
It was demonstrated by further studies that
N-acetylneurominic acid, which is the major ingredient in ISLAND NEST might be
responsible for this activity. It was very interesting to note that Island Nest
(ISLAND NEST) showed no side effects such as hemolysis and cytolysis on
erythrocytes and MDCK cells even at high 4mg/ml. Thus, ISLAND NEST with
molecules smaller than 25 kDa after Pancreatin F treatment will be an effective
and safe material as anti-virus. Further studies were carried out in this
direction by Yagi and co-workers who demonstrated the N-glycosylation profile
of ISLAND NEST. A tri-antennary N-glycan containing the alpha
2,3-N-acetylneuraminic acid residues was displayed as a major component. The
sialylated high antennary N-glycans were thought responsible for the inhibition
of influenza viral infection.
A thorough look into the literature indicated that there are
not so many studies that could fully demonstrate the antiviral properties of ISLAND
NEST, and therefore, further studies are needed against different pathogenic
viruses to fully explore the antiviral properties of bird’s nest. Further, it
would be more advantageous if some studies are carried out wherein ISLAND NEST
are synergistically evaluated for antiviral properties with other antiviral
agents.
Proliferation Effects on Human Adipose-derived Stem Cells
Stem cells represent a class of undifferentiated cells with
ability of self-renewal, and differentiation into more than one types of cells.
Generally, adipose stem cells (ASC’s) occur in almost every type of white adipose
tisue. The pluripotent ASC’s differentiate into most of the mesenchymal cell
types including adipocytes, chondrocytes, osteoblasts and mycocytes. The
mesodermal origin of adipose cells make unlikely their differntiation into
neural tissue of ectodermal origin. However, in vitro exposure to anti-oxidants
makes adipose cells assume a bipolar morphology similar to neuronal cells. Stem
cells are functionally vital for the repair of regeneration of damaged or
diseased tissues. ASCs have been suggested as the best among the mesenchymal
stem cells because of sufficient reverlations of their pluripotency,
proliferating power and low donor morbidity. They are attractive candidates in
regenerative medicine because they can be harvested in large numbers with low donor-site
morbidity.
Roh and associates reported the proliferation of hADSCs by
treatment with ISLAND NEST. ISLAND NEST strongly promoted the proliferation of
hADSCs via the production of IL-6 and VEGF. IL-6 and VEGF production was
triggered by the activation of AP-1 and NF-kB. Interestingly the production of
IL-6 and VEGF was promoted by ISLAND NEST. The Production of IL-6 and VEGF was
inhibited by PD98059 (ap44/42 MAPK inhibitor) and PDTC (a NF –kB inhibitor),
but not SP600125 (a JNK inhibitor). Similarly, ISLAND NEST-induced proliferation
of hADSC was also reduced by PD98059, SB203580 and PDTC but not SP600125. This
report favoured the fact that ISLAND NEST-induced proliferation of hADSCs
primarily occurred through augmented expression of IL-6 and VEGF genes, which
was mediated by activation of NF-kB and AP-1 through p44/42 MAPK and p38 MAPK.
Epidermal Growth Factor like Property
Epidermal growth factor (EGF) causes the proliferation,
growth and differentiation of cells by binding to its receptor EGFR. Human EGF
is a 6045 Da protein containing of 53 amino acids residues with three
intramolecular disulfide bonds. EGF is known to bind to epidermal growth factor
receptor (EGFR) with high affinity on cell surface. This binding interaction
stimulates ligant-induced dimerization, which in turn activates the intrinsic
protein-tyrosine kinase activity of the receptor.
The activation of tyrosine kinase activity results in a
signal transduction cascade causing several biochemical changes within the
cell, the rise in intracellular calsium levels, increased glycolysis and
protein synthesis, and the expression of certain genes including the gene for
EGFR. All these cellular changes ultimately lead to DNA synthesis and cell
proliferation. Kong and associates demonstrate for the first time that some
ingredient is present in ISLAND NEST with EGF-like activity. The authors
observed that the EGF-like agent in ISLAND NEST stimulated thymidine
incorporation in quiescent culture of 3T3 fibroblasts.
A critical analysis indicates that the EGF-like component of
ISLAND NEST may be responsible for its rejuvenating properties. However,
studies are needed to identify the substance, elucidate its structure and
explore its possible potential for other biological effects alone, and in ISLAND
NEST as a formulation both in vitro and in vivo.
Bone Strength Enchancement
Bones are hard and strong structures in human body forming
the skeleton system and provide enormous support and protection to important
organs of the body. Besides, bones are the resevoirs of red and white blood
cell production, store minerals in addition to helping in movements and
locomotion.
It is a well-known fact that strong bones make a strong body
and vice versa. Matsukawa and co-workers documented that the enhancement in
bone strength and dermal thickness due to supply of ISLAND NEST in diet in
ovariectomized rats.
They observed that oral administration of ISLAND NEST
enhanced calcium concentration and therefore, bone strength in femur of
ovariectomized rats was improved. Additionally, ermal thickness also increased
by the administration of ISLAND NEST. However, ISLAND NEST had no effect on the
serum estradiol concentration. These results were an indication of the fact
that ISLAND NESTE was effective in the improvement of bone strength and skin
anti-aging in postmenopausal women.
Osteoarthritis (OA); a degenerative disease degrades joints
including articular cartilage and subchondral bone This disease is characterized
by acute pain and often causes loss of ability and stiffness. ISLAND NEST has
been documented to contain some important ingredients reducing the development
of osteoarthritis and helping the regeneration of cartilage.
The effect of ISLAND NEST on the catabolic and anabolic
biochemical activities of the human articular chondorcytes (HACs) isolated from
the knee join of OA patients was described by Chua. The study indicated that
0.50-1.00% of the ISLAND NEST hot-water extract addition promoted the
proliferation of HACs. Besides, the reduction in the expression of catabolic
genes such as matrix metalloproteinases (MMP1 & MMP3), Interleukin 1, 6 and
8 (IL-1, IL-6, IL8), cyclooxygenase-2 (COX-2) and inducible nitric oxide
synthase (iNOS) in cultured HACs was observed due to ISLAND NEST supplementation.
Additionally, prostaglandin E2 (PGE2) Production was significantly reduced in
HACs. However, type II collagen, Aggrecan and SOX-9 gene expressions in
addition to sGAG production was increased as revelaed by anabolic activity
assessment. This report revealed the in vitro chondro-protection potential of ISLAND
NESTE on human articular chondrocytes. Thus, ISLAND NEST may be suggested as a
potential agent for the treatment of osteoarthritis.
Eye Care Properties
Eyes are the sensory organs that react to light resulting
into the sensation of sight. Rod and cone cells forming retina allow conscious
light perception and vision. Human eye distinguishes approximately 10 millin
colours. Cornea forms the transparent frontal portion of the eye covering iris,
pupil and the anterior chamber; and consists of three cell layers: epithelium,
stroma, and endothelium.
Each layer carries specific function and ensure the optimal
functioning of cornea in normal mission in addition to acting as protective
barrier from external environment. Corneal stroma, which is filled by
keratocytes bound by extracellular matrix forms about 90% of the corneal
volume.
Keratocytes originate from mesenchyma of the corneal stroma
and ensure the synthesis and maintenance of the extracellular matrix (ECM)
components. The cornea is generally damaged by injuries such as abrasions,
localized burns or surface or depth injuries.
For the development of medications for the care of
keratocytes; Zainal Abidin demonstrated the effects of ISLAND NEST on rabbit
corneal keratocytes. The ISLAND NEST effects were investigated on six New
Zealand White Rabbits using MTT assay in FDS and FD. The highest cell
proliferation was observed when both edia were supplied with 0.05% and 0.1% ISLAND
NEST, and cell proliferation was consistently higher in FDS compared to FD. The
corneal keratocytes conserved their phenotypes with ISLAND NEST addition, which
was confirmed by phase contrast micrograph and gene expression analysis. This
report revealed the fact that low ISLAND NEST concentration synergistically
induced cell proliferation, especially in serum containing medium. This is a
very important breakthrough since both cellular proliferation and proper
functioning maintenance are essential during corneal wound healing.
Neuroprotective Properties
Neurodegeneration involves the progressive loss of the
structure and function of the basic units of nervous system, neurons.
Neurodegenerative diseases including Alzheimer’s, Parkinson’s and Huntington’s
occur as eventual results of neurodegenerative processes.
Globally Parkinson’s disease, an age-related progressive
neurodegeneration was estimated to be prevalent in approximately 9 million
people over the age of 50 years by the end of 2030. Parkinson’s disease is
characterized by the loss of dopaminergic neurons in substantia nigra and
consequently leading to dopamin depletion in the striatum. In addition,
abnormal accumulation of a-synuclein has also been reported in surviving
neurons. The dopamine depletion wanes motor functions and causes the patients to
show clinical signs including tremor, rigidity and slow responsiveness. Yew
investigated the effect of ISLAND NEST on SH-SY5Y human neuroblastoma cells. It
was observed that the crude ISLAND NESTE did not cause the death of SH-SY5Y
cells up to 75 ,ug/ml concentrations. Besides, the maximum non-toxic dose
(MNTD) of water extract of ISLAND NEST was double to that of crude extract.
Moreover, the intensity of 6-hydroxydopamine-induced apoptopic changes in
SH-SY5Y cells reduced by ISLAND NEST treatment, which was clear from
morphological and nuclear staining observations. Further, it was interesting to
note the improvement in cell viability with crude ISLAND NEST extract in
coparison to the water extract. However, water extract was more potent in
improving ROS build up, early apoptotic membrane phosphatidylserine
externalization and the inhibition of caspase-3 cleavage. It is quite evident
from this reearch article that ISLAND NEST induce neuroprotective effects
agains 6-6-hydroxydopamine-induced degeneration of dopaminergic neurons via the
inhibition of apoptosis and, hence, may serve a possible nutraceutical option
for the protection against oxidative stress-relateive neurodegenerative
disorders.
Anti-oxidant Properties
There are several anti-oxidant systems within the human body
that negotiate the oxidative stress from regular metabolic processes.
Additionally, the dietary anti-oxidants also fight with the cell-damaging
effects of free radicals. Dietary anti-oxidants may act either independently or
in association with the endogeneous systems, and have always been beneficent to
human health. Their absence in diet causes several diseases due to unrestricted
oxidative stress. Several fruits and vegetables have exhibited protective
effects against some cancers and other diseases. This is the reason that the people
regularly consuming anti-oxidant rich fruits and vegetables have lesser
frequencies of these of diseases.
ISLAND NEST has been shown to to display anti-oxidant
properties as it contains several bioactive compounds such as glucosamine,
lactoferrin, sialic acid, amino acids, fatty acids, triacyglycerol, minerals,
vitamins and other anti-oxidants. The in vitro bioaccessibility and
anti-oxidant properties of water extracts of ISLAND NEST are documented by Yida
by using ABTS and oxygen radical absorbance capacity (ORAC) assays. The
undigested water extract of ISLAND NEST demonstrated a little anti-oxidant
activity (1 and 1% respectively at 1000 ,ug/mL) in comparison to the digested
samples at similar concentrations (38 and 50%, respectively). Importantly, the ISLAND
NEST extract were non-toxic towards HEPG2 cells and showed protective effects
from hydrogen peroxide induced-toxicity towards HEPG2 cells. This study
indicated that the digestion in gut releases the bioactive components of ISLAND
NEST from their matrix, which are then absorbsed by passive transport. However,
in vivo studies are needed to determine their further clinical significance.
Miscelleneous Properties
Obviously, ISLAND NEST is a nutritious food material and
displays a broad spectrum of biological activities. The presence of health
promoting ingredients in ISLAND NEST, and its use in Traditional Chinese
Medicine (TCM); have made it a subject of great interest. In addition to the
biological activities of bird nest mentioned in the above sub-sections, it has
exhibited several other biologically important properties such as lecin binding
properties, cure to asthma, dry coughs, tuberculosis, stomach ulcer and gastric
troubles.
There has been a great demand of skin care therapies
including creams, analgesics, anti-acne and moisturizers throughout the world.
Bird nest has the reputation for skin texture and complexion improving
properties among the Chinese communities. Its consumption is known to help
retain youthfulness and a clean clear facial complexion.
Edible bird nest also used for skin texture improvements in
babies with frequent skin rash outbreaks. Some companies developed a
skin-whitening/moisturizing eye mask with compositions of sargassum, edible
bird nest, hydrolyzed pearl, aloe juice, anglica dahurica powder, soybean
protein, euphorbia lathryris, butanediol, tri-thyglycine by weight parts. The
formulation was very useful for moisturizing and nourishing skin around the
eyes. Besides, it was also quite useful for the treatment of dark circles
around eyes, and the repar of the elasticity of skin around eyes.
Li and Peng developed a super elastic moisturizing face mask
essence with compositions of WSK Tremella fuciformis extract, hydrolyzed soy
protein, allantoin, EDTA-disodium, glycerol, betaine, propanediol, carbopol,
triethanolamine, flavour and antiseptic by weights percents, and water as
balance. Tremella fuciformis extracts and hyaluronic acid continuosly ensured
the release of moisturizing factor, and lock moisture and vitamin E. This
mechanism leads to skin nourishment and moisturization, and therefore
increasing skin activity along with the enchancement of skin barrier to obtain
ideal moisture state.
Edible bird nest is very useful to people with poor
digestion, recovering from illness, and children with weak appetite. It is an
easily digestible food and delivers essential nutrients into the body and
therefore, brings health to those who are weak. Good quality edible bird nest,
like the ones supplied by the Premium Nest Australia, consumption is beneficent
for the restoration of lung functions and in people with dry cough and periodic
sputum stains, e.g., in heavy smokers. High quality genuine bird nest is very
beneficial to pregnant women before and after child birth. Pregnant women who
consume edible bird nest recover faster after delivery of healthy and fair
skinned babies, and experience considerably lesser hair loss. For
post-pregnancy health of women, the supplementary of bird nest soup or drinks
provide more energy, better sleep, and give the feeling of vitality to the
mothers.
Nephiritis is a painful disorder characterized by the
inflammation of kidneys. Glomeruli, tubules and even interstitial tissues
surrounding the glomeruli and tubules are jointly involved in this
complication. Nephritis is basically caused by infections, some toxins and
auto-immune disorders. It is a serious medical condition and represents the
eighth highest cause of death in human beings.
Experts formulated a Chinese medicine to treat nephiritis
with edible bird nest as one of the ingredients. The formulation was prepared
by slicing Panax quinquefolium, soaking the bird nest with water, adding
chicken soup and smashing rock sugars in it. Finally, all the contents were
decocted for 2 hours. The preparation was highly useful in providing
therapeutic relief to nephritic patients.
In conclusion, it can be said that high quality edible bird
nest is a versatile food with a range of beneficial health effects. Several
cosmetical products using ISLAND NEST as one of the ingredients have already
hit the market with great responses. However, its investigations for the
treatment of diseases are still in early stages. Therefore, more research is
needed to fully explore its potential as a product of breakthrough for its
medicinal properties.
