Topic: Why are pharmaceutical factories inconsistently vegetarian?

[Matthew]

When chemicals become available, pharmaceutical factories stop requiring vegetables. But after 1975, they start requiring vegetables again. The .dat file does not explain why. Is anyone able to explain the thinking behind this, please?

1860-1920:

Code: [Select]

InputGood[0]=vegetables
InputCapacity[0]=30
InputSupplier[0]=2
InputFactor[0]=80
# Chemicals are not currently available before 1910;
# but many pharmecutical products were made with coal tar.
InputGood[1]=Kohle
InputSupplier[1]=1
InputCapacity[1]=50
InputFactor[1]=20
1920-55:

Code: [Select]

InputGood[0]=Chemicals
InputCapacity[0]=64
#InputSupplier[0]=1
InputFactor[0]=100
1955-75:

Code: [Select]

InputGood[0]=Chemicals
InputCapacity[0]=96
#InputSupplier[0]=1
InputFactor[0]=100
1975-end of game:

Code: [Select]

InputGood[0]=Chemicals
InputCapacity[0]=80
#InputSupplier[0]=1
InputFactor[0]=67
InputGood[1]=vegetables

Homeopathic remedies? 

Levity aside, I don't know the specific reason, but I'd have thought that vegetable and other plant-based extracts with potential medicinal uses, such as castor oil, would be available throughout the 20th Century. I don't know if they would count as mainstream medication however; very common medicines like ibuprofen and aspirin appear to be completely synthesised.

EDIT: Actually, my first comment may not be so far from the truth! Perhaps the the reappearance of vegetables is indeed intended to represent the sort of products available at 'health food' chains such as Holland & Barrett?
