More Science Research about agarwood leaves

Nik Noor (2014) and his research team conducted a study in 2014 on the antioxidant activity of Aquilaria Malaccensis leaf extracts (agarwood leaf). They discovered that these leaves possess significant antioxidant properties.

Infected Aquilaria Species:

Infected Aquilaria species are highly sought after for their oil and resin, used in fragrances and incense. Their leaves are also valuable for their medicinal properties.

Phytochemical Screening:

Preliminary tests revealed that agarwood leaves contain alkaloids, terpenoids, flavonoids, steroids, saponins, and tannins. These compounds support antioxidant activities and have various medicinal benefits, including analgesic, antipyretic, anti-inflammatory, anti-hyperglycemic, and antimicrobial properties.

Constipation Relief:

A study conducted over 14 days with rats (approved by the Animal Investigation Committee of Gifu Pharmacological University) showed that agarwood leaf extracts increased stool frequency and weight without causing diarrhoea. Genkwanin-5-O-beta-primeveroside likely plays a key role in this laxative activity by acting on acetylcholine receptors in a low-fibre diet model.

Sleep Aid:

Agarwood leaves also aid in sleep. One reviewer noted, "The time of day you drink this tea is important! It seriously makes you sleepy. The first time I drank it at noon, and I wanted to nap all afternoon. The second time I had it before bed and slept like a baby. This tea also affects bowel movements."

In the other hand, sleep aid is another benefit agarwood leaves offer. 

One of our reviewers say "............. The time of day you drink this tea is also important! It seriously makes you sleepy. The first time I drank it at noon and I just wanted to nap all afternoon. The second time I had it before bed and slept like a baby. Also, keep in mind that this tea does indeed affect your bowel movements..............." (teaviews.com)

Preparation Tips:

Agarwood leaves can be bitter if too much is used. For a 250 ml cup, 5 to 8 tea balls are sufficient. Adding lemon, fresh or dried orange, or mixing with green tea can improve the flavour. The natural chemical composition of agarwood leaves promotes relaxation and calmness when consumed.

Agarwood leaves can be mixed with other teas, dried orange, strawberries, or other fruits to vary the taste.
