The truth of God delivered by his Messenger is like wormwood to those that do not wish to accept it and ambrosia to those that can.
Prophet Isaiah explains it well. "These are rebellious people, deceitful children, children unwilling to listen to the LORD's instruction. They say to the seers, "See no more visions!" and to the prophets, "Give us no more visions of what is right! Tell us pleasant things, prophesy illusions. Leave this way, get off this path, and stop confronting us with the Holy One of Israel!"Isaiah 30:9-11
The truth is like wormwood to those that do not wish to hear the word of God and follow his instructions. Here is a discussion with a person that wished to know and understand what Wormwood means.
Literalist: Wormwood is described as a star, so, it’s a star. Probably the same one described elsewhere as the destroyer, the frightener, brown dwarf, planet-x, planet Nibiru, which was written about by Zecharia Stitchin. The object or objects appearance heralds the beginning of ‘The Day of the Lord’ and will be preceded slightly by the rapture. I once heard that wormwood translated into Russian is ‘Chernobyl’ but I don’t know whether that is true or not.
Messenger: In biblical times calling somebody a worm was in relation to a person that was not very nice to others. It was also a description for a carnal person with a callous heart that attacked others verbally with malicious intent. The worm is earthbound and licks the dust of the earth and the serpent can also be found in the bible.
The wormword plant is a medicinal plant but it is also bitter, in the Greek text it is ‘Apsinthos’ the name of a star’. The word Chernobyl properly refers to Artemisia vulgaris known as Mugwort. In Russian culture and its modern poetry, wormwood is viewed as a symbol for a ‘bitter truth’. It poignantly addresses delusional beliefs and illusionary ideologies. The word "wormwood" comes from Middle English "wormwode" or "wermode". The form "wormwood" is influenced by the traditional use as a cure for intestinal worms.  The plant itself has a bitter taste.
In this context one can understand how the truth awakens the worm within a person when they hear the truth; that is why some people react to truth in an adverse way, start swearing, name calling and make accusations. A reactionary person is indicative of a person that has not healed or become whole. A healed and whole person is peaceful, graceful and they are dignified in their responses to those that have the worm wriggling within them. This concept was well known in ancient Judaism and that is why Jesus called his accusers vipers and blind guides. Jesus knew that those that stood against him knew the meaning of what he was saying to them. In modern day we use the term 'The light triggers the darkness and the darkness triggers the light until there is no more darkness left".
Mugwort is a perennial plant found in Europe and it has been used medicinally since ancient times for digestive, gout and skin problems. This flower essence can open faculties that have not been used before and it is a spiritual tonic for the spiritual body.  Flower essences work on a vibrational level and a lot of information in the bible is about consciousness as one would appreciate to find in spiritual texts.
Literalist: It probably means a comet filled with toxic bitter compounds with the same effect as wormwood will fall to Earth. Is it supposed to be a giant bundle of the planet known as wormwood? Well, maybe. Seeing Earth destroyed by a square manatee from space would be pretty epic….
Messenger: In spiritual symbology Worm = Death, dissolution, the earth. The serpent is sometimes called the 'great worm'. Thomas Aquinas reasoned that, since animals are not granted immortality, the undying "worm of the damned" must be the worm of regret and conscience rather than a physical worm (Summa Theologica by Thomas Aquinas). Wormwood = Bitterness, distress, torment sacred to Aries/Mars. 
WORM IN THE WOOD OF THE TREE OF LIFE
People are not tormented by the truth they are tormented by the memories held in their souls/consciousness because the truth triggers that which is held within them until the day comes when they have the willingness to heal it.
The truth itself is not bitter it is the impact of the truth that brings forth what is held inside people. There is a saying that some people are "wooden headed" in other words the density of their rigid belief systems do not allow the truth to enter in. In biblical times they were called callous, hard and stubborn hearted.
So one could say that there is a "worm in the wood" of many people who live in an earthly reality, and when the truth is told the worm rears its head and exposes itself to itself; and those that watch it emerge out of the tree of life experience. It is memories that are triggered by the truth, Jesus called the root causes of the core issues demons because he knew that people were haunted by their memories that create their emotive reactions and fears. He also told people with rigid belief systems that they were blind, deaf, dumb and lame. Jesus knew that people had to become fluid to be and flow in harmony with God's creation. He knew that change is as natural as the seasons of nature and that when the literal orthodox thinkers refuse to change that they then come to taste death e.g. cancer.
The Revelation states that "A third of the waters turned bitter, and many people died from the waters that had become bitter". Man is made of 70-80% water and we know that water holds memories. It goes without saying that people who are bitter do harm to the self and their own biology. In most cases humanity co-create their own disease with their thoughts, beliefs, attitudes and perceptions. This truth is now exposed by cutting edge scientists.
Truth is also being revealed by scientists and other academics and philosophers. This will impact on current illusions of those that live in a purely material existence. 1/3 of the people would also tie up with other aspects of the book of revelation. When people discover that they have invested their lives in theology and education that is an illusion, many will be bitter that they are paying the bill for their literal and carnal mindset. When people come to know that their thoughts determine the activity of their genes, then there is no place to run or hide, there is also nobody to blame for co-creation. Once that realisation is taken on board it could have a huge impact on many people. The medical profession now accept that 85% of all disease is co-created by stress; in other words it is self-created.
Where else do we find wormwood? In Hebrew it is a metaphor 'La`anah'. "But in the end she is bitter as wormwood, Sharp as a two-edged sword." Proverbs 5:4
For the word of God is living and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.Hebrews 4:12
"For those who turn justice into wormwood and cast righteousness down to the earth." Amos 5:7
What is a Star? It is a shining light not a planet. These are spiritual texts, talking in spiritual words, about spiritual realities. Sadly, many literaists try to make them fit into material/literal realities. Without the knowledge of spiritual symbology one can never truly comprehend spiritual texts, spiritual wisdom or the nature of this kind of prophecy. In spiritual symbology a star represents the presence of divinity, the highest attainment, a messenger from God. Hope shinning in the darkness, Stars are attributed to the Queens of Heaven who are often crowned in stars. The Star is pre-eminently the symbol of Ishtar, or Venus as morning and evening Star. It is also a symbol of constancy. In Chinese, a star or stars with the sun and moon depict the spiritual wisdom of rulers. There is a whole page of spiritual meanings of a star in different cultures down the ages, and most of these have absolutely nothing to do with planets or comets. 
SIMPLY RED - STARS
Literalist: If we take the opposite approach and look at it in a highly interpretative and non literal approach, its hopeless. There are so many, many possible hidden meanings; we might as well argue how many angels can dance on the head of a pin. One of this near-infinite subset of possible spins you can put on the text may be right, but I don’t know how to construct a test to read the author’s mind….
Les Miserables - Stars
Messenger: Exactly, so why do innocent people misuse so much time using literal analysis on spiritual texts that require lateral thinking and mystical understanding and insight? Spiritual texts are not literal texts, when the words are literal, they are very specific and do not require a mystic to understand them. Only a mystic can get very close to understanding another mystics visions, although it is clear that Apostle John did not really understand them himself.For if he did he would have provided a commentary for others to understand.
It is stated in the Dead Sea Scrolls by the scholar Geza Vermes that the Qumran sectaries argued that it was impossible to understand the full meaning of the Prophets, without an inspired spiritual interpreter, due to the Prophets themselves being innocent of the fullness and sheer importance of what they said and wrote. Only mystics can truly understand mystical states and visions.
God said "Healing is the get out of jail card. Healing is the path to salvation and love is the way".
The Star is the light of truth, the Spirit of Truth is a Sacredstar. A bright star shinning in the darkness like a diamond. It has many facets and brings forth many colours given by God our heavenly Father.
A true follower of Jesus Christ becomes a healer like their role model. They follow him and walk in his footsteps and in so doing they come to know him and his ways. Eventually, the day comes when you have allowed him to lead you through the spheres he called the heavenly streams to the Father.
There are many heavens and many different worlds.
