The galaxy in Starfield is filled with all kinds of crafting materials, whether organic or inorganic, and these are needed to craft valuable items or complete quests. Biosuppressant is one of these items and an exotic resource that is rarely found when harvesting plants.
If you have traveled to the clinic, you may have been tasked with delivering certain organic resources to Lara Darvish. Biosuppressant is on that list, and with thousands of planets in the galaxy, it can be challenging to find flora that can be harvested for it. However, there are a few other solutions.
How To Get Biosuppresant
There are several known methods to obtain Biosuppressant in Starfield:
- It can be purchased from numerous vendors across the Volii, Alpha Centauri, and Sol Systems.
- By harvesting them from flora while exploring planets.
- As random drops in loot containers.
The most reliable method to obtain this resource is through traders, as the chances of acquiring Biosuppressant through other means are very low.
Where To Find Biosuppresant Vendors
You can purchase Biosuppressant at numerous locations, thanks to several traders who will sell this item. If you need more, you can replenish a trader's inventory by traveling to a new star system and sleeping for twenty-four hours.
Since you can do this on your ship, we recommend landing on a planet in a new system before returning to the trader. Using this method, you can quickly acquire large quantities of Biosuppressant in a short amount of time.

What Are Biosuppresants Used For
In addition to being used as an exotic crafting component, Biosuppressants are also needed for research by Dr. Lara Darvish at the clinic's space station. She explains that they can be used to prevent secondary infections, but she requires additional samples.
Then she will task you with collecting samples of Biosuppressant in exchange for credits. Dr. Darvish will pay more than they actually cost, making it an easy way to earn credits and experience points.
