3.2. Potential as Medicinal Crop Utricularia is recorded to be edible and high in nutrients. Some species used as folk remedies are mildly astringent and diuretic. U. caerulea is used to dress wounds while U. bifida is used to treat urinary diseases. Although yet to be widely researched, the medicinal potential of this species-rich genus is immense. In Peninsular Malaysia, U. bifida and U. minutissima are pioneers of open disturbed wetland and are often locally abundant, although U. caerulea is increasingly rare. U. bifida is highly suited for acidic damp soils. Neither chemical nor organic fertilisation is necessary. It can be cultivated without having to modify bad drainage or liming the soil to increase pH, therefore, it is a suitable alternative for small-scale herb cultivation on nutrient-poor, waterlogged soils.
You make some perfectly valid points, the only thing I take issue with is
So, I do historical reenactment and one of my focuses is the history of money. Money has been in use, in some form or another, all over the world, for about ten thousand years. Roughly twice as long as written language.
Again, I agree with what you’re saying about time and how important it is. But go back to when humans had huge swaths of free time and you still find money. It’s just INSANELY useful.
