Psalm 58:6“It happened when Joram saw Jehu, that he said, “Surely there is peace, Jehu?” Jehu said, “How is there peace while the immorality of Jezebel, your mother, and her many sorceries remain?”” (4 Kingdoms (2 Kings) 9:22, LES)
A second translation of this last one:“Do not strive for death in the wandering of your life, or invite destruction[ὄλεθρος, destruction, ruin] by the works of your hands, because God does not cause death or delight in the destruction[ἀπώλεια, destruction] of living ones. For he created all things to exist, and the generations of the world bring salvation, and there is no poison of destruction[ὄλεθρος, destruction, ruin] in them, and the kingdom of Hades is not on the earth; for righteousness is immortal. But the ungodly, by their hands and words, summoned it; considering it a friend, they pined away and made a covenant with it, because they were worthy to take part with it.” (Wisdom of Solomon 1:12–16, LES)
12 Court not death in the error of your life;
Neither draw upon yourselves destruction by the works of your hands:
13 Because God made not death;
Neither delighteth he when the living perish:
14 For he created all things that they might have being:
And the products of the world are healthsome,
And there is no poison of destruction in them:
Nor hath Hades royal dominion upon earth;
15 For righteousness is immortal,
〈But the gain of unrighteousness is death〉.
16 But the ungodly by their hands and words called him unto them:
Deeming him a friend they were consumed with love of him,
And they made a covenant with him,
Because they are worthy to be of his portion.
-Apocrypha of the Old Testament, Wisdom 1:12–16
Speaking of the conquest of Caanan:
Speaking of Moses before Pharaoh and the magicians:“For also the old inhabitants of your holy land[Canaanites], hating them because of their hostile practices, works of sorceries and unholy rites, and merciless murderer of children, and a feast of eating the entrails of human flesh and blood from initiates from the midst of an orgy, and parents who are murderers of helpless souls, you wished to destroy[ἀπόλλυμι, destroy] them through the hands of our ancestors[Israel]; so that the land, most precious of all before you, might receive a worthy colony of the children of God.” (Wisdom of Solomon 12:3–7, LES)
Speaking of the positive side, non-occultic use of the word as a medicine:“For although they disbelieved everything because of the sorcery, at the destruction[ὄλεθρος, destruction, ruin] of the firstborn, they acknowledged that this people was God’s son.” (Wisdom of Solomon 18:13, LES)
“A faithful friend is the medicine of life, and those who fear the Lord will find him.” (Sirach 6:16, LES)

Speaking of the angels who copulated with women before the flood:
And that's just the old testament Septuagint“Then they took for themselves women, each of them choosing a woman for themselves. They began to go to them and defile them. And they taught them sorcery and enchantments and cutting of roots and explained herbs to them.” (Enoch 7:1, LES) (in another place in Enoch it talks about how the angels knew some of the secrets of the earth)
“Now the deeds of the flesh are evident, which are: immorality, impurity, sensuality, idolatry, sorcery, enmities, strife, jealousy, outbursts of anger, disputes, dissensions, factions, envying, drunkenness, carousing, and things like these, of which I forewarn you, just as I have forewarned you, that those who practice such things will not inherit the kingdom of God.” (Galatians 5:19–21, NASB95)

In the positive, medicinal sense:
...with an undisturbed mind, breaking one bread, which is the medicine of immortality, the antidote that we should not die but live in Jesus Christ throughout all [ages/time]. -Ignatius to the Ephesians 20:2
Therefore I urge you (not I, but the love of Jesus Christ) only make use of Christian food, and abstain from the foreign plant, which is heresy. 2 These people, while seeming trustworthy, mingle Jesus Christ with themselves like those who produce a deadly drug with honeyed wine, which the ignorant one gladly takes hold of in evil pleasure, to his death. -Ignatius to the Trallians 6:1-2
5.1 But the way of death is this. First of all, it is filled with evil and cursing, murders, adulteries, expressions of lust, acts of sexual immorality, thefts, idolatries, acts of magic, use of potions, robberies, false witnessing, acts of hypocrisy, acts of duplicity, deceit, pride, malice, stubbornness, greediness, abusive language, jealousy, arrogance, haughtiness, boastfulness. 2 Persecutors of the good, hating the truth, loving the lie, not knowing the reward of righteousness, not joining the good or the righteous judgment, not caring for the good but for the evil, from whom gentleness and patience are far removed, loving what is worthless, pursuing reward, not having mercy on the poor, not toiling for the downtrodden, not knowing the one who made them, murderers of children, corrupters of the creatures of God, rejectors of the needy ones, oppressors of the afflicted, defenders of the rich, lawless judges of the poor, people steeped in sin. Be delivered, children, from all such as these. -Didache 5:1-2
The Shepherd of Hermas20.1 But the way of the Black One is crooked and filled with cursing, for it is the way of eternal death with punishment, in which are the things which destroy their soul: idolatry, arrogance, ⌊arrogance in an influential position⌋, hypocrisy, acts of duplicity, adultery, murder, robbery, pride, transgression, deceit, malice, stubbornness, use of potions, magic, greediness, lack of fear of God; -Barnabas 20:1 (The Didache was probably a part condensation of the Apostle Barnabus' epistle)
So the word is actually used a lot. But its hard to tell what word is there under the English translations.7 Therefore I speak now to the leaders of the Church and to those ‘who take the chief seats.’ Be not like the sorcerers, for sorcerers carry their charms in boxes, but you carry your charms and poison[ἰός, poison] in your hearts. 8 You are hardened, and will not cleanse your hearts, and mix your wisdom together in a pure heart that you may find mercy by ‘the great King.’ Hermas - Similitudes 3.9.7ab
