What methods can be used to test and identify vetiver essential oil?What are the benefits and uses of lalang grass rhizome? Let's take a look and learn about it together.
How to Identify Vetiver Essential Oil:
Observe the skin's reaction: The purer the essential oil, the stronger its penetration, and the stronger its ability to regulate the skin's blood circulation. So before buying, you can apply the essential oil diluted with a carrier oil to the back of your hand, then massage it with your fingertips for a few seconds. If the essential oil is quickly absorbed and leaves no trace of oil, then this essential oil is of superior quality. On the contrary, if you can see that the essential oil leaves behind some grease-like residue, then this essential oil is very likely fake, or has had many additives mixed in, resulting in very low purity.
Smell the fragrance: Pure natural essential oils have a fragrant, pure scent. Synthetic fragrances, however, have a scent mixed with many different odors, so if at first sniff it feels pungent or uncomfortable, it is very likely that the essential oil is fake. If it smells comfortable and does not cause dizziness, only then could it be real.
Check the container: Essential oils evaporate easily, so they must be stored in dark glass bottles to ensure the purity of the essential oil. The corrosive nature of essential oils also dictates that they cannot be placed in plastic bottles. So once you find a product with essential oil in a plastic bottle, you must never buy it.
1. Cools the blood and stops bleeding
Lalang grass rhizome is sweet in taste and cold in nature, and is especially good at cooling the blood and stopping bleeding. It is mainly used for blood syndromes caused by external pathogens such as wind, heat and dryness invading the human body, damaging the blood vessels with pathogenic heat, forcing the blood to move abnormally, or caused by chronic illness or heat disease.
2. Clears heat and relieves strangury
Often caused by eating too much pungent, hot, rich and sweet food, or excessive alcohol consumption, which brews damp-heat that pours downward into the bladder, causing the bladder's qi transformation to fail, or by unclean genital area allowing foul turbid damp pathogens to invade the bladder, brewing damp-heat and developing into strangury. Heat strangury mainly manifests as: frequent and scanty urination, burning and stabbing pain, yellow-red urine color, urgent distending pain in the lower abdomen, or chills and fever, bitter taste in the mouth, nausea and vomiting, waist and abdominal pain, etc. Lalang grass rhizome has the effect of clearing heat and promoting urination.
3. Damp-heat urinary retention
One of the effects of lalang grass rhizome is clearing heat and promoting urination, so it can be used for excess heat syndromes of difficult urination caused by heat pathogens.
4. Drains dampness and treats jaundice
When damp-heat pathogens invade the human body, the body's dredging and discharging functions fail, and the damp-heat overflows onto the skin, developing into jaundice. Or when pestilent heat pathogens steam the liver and gallbladder, their dredging and discharging power is lost, and the stagnant heat is not resolved, developing into jaundice. The syndrome presents as yellowing of the body and eyes like the color of an orange, with a bright color, fatigue and poor appetite, nausea, vomiting, abdominal distension, abdominal pain and hypochondriac pain, and yellow urine like strong tea, etc. Applying lalang grass rhizome can clear and drain damp-heat, promote urination, and treat jaundice.
5. Disperses wind and promotes urination
Wind-water edema is caused by wind-heat pathogens attacking from outside; wind lodges in the lungs, the lungs fail to diffuse and descend, the water passages are blocked, so wind blocks and water is obstructed, wind and water wrestle with each other, overflow onto the skin, and develop into the syndrome of edema. Its manifestations are: puffy eyelids, followed by swelling of the limbs and the whole body, with a rapid onset, soreness and heaviness of the joints, difficult urination, or aversion to cold, fever, sore and swollen throat, yellow coating, and rapid pulse. Use lalang grass rhizome to clear and diffuse wind-heat, promote urination, and reduce swelling.
